Abstract
The invention relates to a transformer substation secondary air switch locking grounded small ground wire which is mainly applied to secondary grounding of devices, such as substation transformers and substation voltage transformers, in transformer substations. The transformer substation secondary air switch locking grounded small ground wire comprises a base, a leaf spring, a wiring pose, a copper wire, a grounding clamp and an insulation sleeve, one side of the base is provided with a buckle and a clamping groove formed by two stopping blocks from top to bottom, the wiring pose is fixed to the other side of the base, the leaf spring is fixed to the wiring pose and sleeved with the insulation sleeve, one end of the copper wire is fixed to the base through the wiring pose, and the other end of the copper wire is connected with the grounding clamp. The transformer substation secondary air switch locking grounded small ground wire can be easily installed in the mode that the leaf spring is in contact with a wiring bolt of an air switch, reliable grounding is achieved, the problem of time and labor wasting caused by damage to or replacement of the air switch is solved, and person electric shock accidents are avoided; meanwhile, the function of preventing mistake switching-on of the air switch is achieved, dual grounding insurance is achieved, and site safety measures are complete and reliable.
Description
Technical field
The present invention relates to the little ground wire of a kind of substation secondary air switch enclosed type ground connection, be mainly used in transformer station and stand with the secondary ground connection of the equipment such as change, voltage transformer.
Background technology
In transformer station, disengagement failure electric current was mainly carried out with insurance with the secondary of the equipment such as change, voltage transformer in station in the past, so the ground connection of secondary device mainly adopts the little ground wire of crocodile clip, fix and the screw that contacts in fuse terminals row reaches the object of reliable ground by clip, thereby while meeting substation equipment maintenance and repair, prevent the safety measure requirement of the anti-power transmission of equipment.Along with air switch in recent years at station with being widely used of the equipment such as change, voltage transformer, there is following shortcoming in Crocodile type earth connection:
1,, because air switch carries connecting groove, the connecting groove of each producer is not of uniform size, the degree of depth differs; The clip that connecting groove bore is little cannot insert connecting groove, and the clip of depth as shallow cannot be fixed, and causing cannot be to secondary device ground connection; Just need to air switch be destroyed or be changed by expanding the method such as connecting groove bore, the increase degree of depth, waste time and energy expensive; Also there are the problems referred to above by the clip of changing Crocodile type earth connection.
2, fix and reliable ground for convenience of Crocodile type earth connection, when air switch is installed, by naked electric wire overlength leakage, easily cause maintenance and operations staff to touch by mistake, cause personnel's electric shock accidents.
Summary of the invention
According to above deficiency of the prior art, the technical problem to be solved in the present invention is: provide a kind of rational in infrastructure, can realize reliable ground, avoid air switch to destroy and the little ground wire of the reliable substation secondary air switch of handling safety enclosed type ground connection.
The little ground wire of substation secondary air switch enclosed type ground connection of the present invention, comprise base, spring leaf, wiring pile, copper cash, earth clip and insulating case, the draw-in groove that one side of base is provided with from top to down buckle and is formed by two blocks, the opposite side of base is fixed with wiring pile, spring leaf is fixed on wiring pile, spring leaf outer cover has insulating case, and copper cash one end is fixed on base by wiring pile, and the other end connects earth clip.
Operation principle and process:
When ground connection operation, first earth clip is clamped to earth electrode, again the draw-in groove that on base, two blocks form is stuck on the handle of air switch, buckle is stuck in the handle of air switch and the gap of shell simultaneously, then regulate the spring leaf with insulating case, spring leaf is inserted in the connecting groove of air switch it is fully contacted with connection bolt, simple several steps operations have just completed equipment reliable ground.
The present invention is directed to the shortcoming of Crocodile type earth connection, adopt air switch enclosed type earth connection to replace the way of contact of old-fashioned earth connection, realize reliable ground by the mode that adopts spring leaf ingress of air switch wire connection bolt, avoid because expanding connecting groove bore, increasing the problem that the degree of depth is destroyed air switch electric wire foreskin, can prevent by mistake closing of air switch simultaneously, be grounded double insurance, site safety measure improved reliable.
The beneficial effect that the present invention compared with prior art had is:
The present invention is rational in infrastructure, can easily install secondary earth connection by the mode that adopts spring leaf ingress of air switch wire connection bolt, and realize reliable ground, stop air switch to destroy or change the expensive problem of wasting time and energy of generation and personnel's electric shock accidents, there is the air switch of preventing simultaneously and close function by mistake, be grounded double insurance, site safety measure improved reliable.
Brief description of the drawings
Fig. 1 is structural representation of the present invention.
In figure: 1, spring leaf; 2, insulating case; 3, base; 4, wiring pile; 5, copper cash; 6, buckle; 7, block; 8, earth clip; 9, handle; 10, air switch; 11, connecting groove.
Embodiment
Below in conjunction with accompanying drawing, embodiments of the invention are described further:
As shown in Figure 1, the little ground wire of this substation secondary air switch enclosed type ground connection, comprise base 3, spring leaf 1, wiring pile 4, copper cash 5, earth clip 8 and insulating case 2, the draw-in groove that one side of base 3 is provided with from top to down buckle 6 and is formed by two blocks 7, the opposite side of base 3 is fixed with wiring pile 4, and spring leaf 1 is fixed on wiring pile 4, and spring leaf 1 outer cover has insulating case 2, copper cash 5 one end are fixed on base 3 by wiring pile 4, and the other end connects earth clip 8.
When ground connection operation, first earth clip 8 is clamped to earth electrode, again the draw-in groove that on base 3, two blocks 7 form is stuck on the handle 9 of air switch 10, buckle 6 is stuck in the handle 9 of air switch 10 and the gap of shell simultaneously, then regulate the spring leaf 1 with insulating case 2, spring leaf 1 is inserted in the connecting groove 11 of air switch 10 it is fully contacted with connection bolt, simple several steps operations have just completed equipment reliable ground.
The present invention is directed to the shortcoming of Crocodile type earth connection, adopt air switch enclosed type earth connection to replace the way of contact of old-fashioned earth connection, can easily install secondary earth connection by the mode that adopts spring leaf ingress of air switch wire connection bolt, and realize reliable ground, avoid because expanding connecting groove bore, increasing the problem that the degree of depth is destroyed or changed air switch, time saving and energy saving, and effectively stop personnel's electric shock accidents, there is the air switch of preventing simultaneously and close function by mistake, be grounded double insurance, site safety measure improved reliable.
