Abstract
Embodiments of the invention provide an uninterrupted device of anti-maloperation in an electrical substation. The device is fixedly installed on a control panel in a control room of the electrical substation and is connected with the control panel through putting a cable in a cable trench. A generator is inserted in a socket of the device. The uninterrupted device of anti-maloperation in an electrical substation can be installed completely at a time. Inserting the generator in the socket of the device can achieve the usage of the device, which brings convenience for overlap joint of the generator cable and raises a comfort level of overhaul.
Description
Technical field
The invention belongs to the power technology field, relate in particular to a kind of electric substation anti-misoperation device that do not have a power failure.
Background technology
It is of crucial importance that electric substation anti-delayed work, have a power failure or lose under the situation of power supply in full electric substation, need adopt the manual operation form that used electric screen is overhauled subject to after upper management department and the personnel's agreement, also need maintenance department that special working power is provided simultaneously.
In practice, be very frequent to the service work of used electric screen, if manual operation is all adopted in each maintenance, not only reduced security reliability, and wasted the maintenance resource.
Summary of the invention
In view of this, the object of the present invention is to provide a kind of electric substation anti-misoperation device that do not have a power failure, can improve the comfort level of maintenance.
For achieving the above object, one embodiment of the present of invention provide a kind of electric substation anti-misoperation device that do not have a power failure, this device is fixedly mounted on the control flow in electric substation control room, and is connected with described control flow by the cable trough payout, is inserted with generator on the socket of this device.
Preferably, be in series with on the generator powered loop two become normally closed contact;
When become and be under the normal operating conditions situation, two become normally closed contact and open;
When become when being in power failure state, two become the normally closed contact closure.
Preferably, described generator is the small silent generator.
Preferably, also be provided with start button in the described generator powered loop.
Electric substation's anti-misoperation in embodiment of the invention device that do not have a power failure can once mounting be finished, and only generator need be inserted in use in the socket of device get final product, is very easy to the overlap joint of generator cable, improves the comfort level of overhauling.
Description of drawings
In order to be illustrated more clearly in the embodiment of the invention or technical scheme of the prior art, to do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below, apparently, accompanying drawing in describing below is some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the do not have a power failure electrical schematic diagram of an embodiment of device of electric substation provided by the invention anti-misoperation.
Embodiment
For the purpose, technical scheme and the advantage that make the embodiment of the invention clearer, below in conjunction with the accompanying drawing in the embodiment of the invention, technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.
Fig. 1 shows the do not have a power failure electrical schematic diagram of an embodiment of device of electric substation provided by the invention anti-misoperation.Wherein, KM1 is a contactor, and HG and HR are signal lamp, and FU is a fuse, and HA and TA are button.
This device is fixedly mounted on the control flow in electric substation control room, and puts control cable by cable trough and be connected with the control flow in control room, is inserted with generator on the socket of this device.
Like this, the electric substation of the present invention anti-misoperation device that do not have a power failure can once mounting be finished, and only generator need be inserted in use in the socket of device to get final product.Be very easy to the overlap joint of generator cable.
In addition, in a preferred embodiment of the present invention, the electrical interlock of casing and used electric screen two road incoming powers.
Particularly, on the generator powered loop, be in series with two become normally closed node 1C and 2C.Under the change normal operating conditions, 1C and 2C are in power failure state (being that contact is opened).The KM1 coil losing electricity in the device that do not have a power failure this moment, the loop of whole device is obstructed, thereby guarantee become under the charged situation, the device that do not have a power failure does not carry out work.
When the change dead electricity (electric substation full institute has a power failure), 1C and 2C closure, the KM1 coil in the device that do not have a power failure is charged, the loop conducting of whole device, the operation of the device that begins at this moment not have a power failure.
Connect two become normally closed node 1C and 2C purpose be: guaranteeing only to become two institutes does not have under the electric situation simultaneously, the power supply that does not have a power failure in the device becomes unique reliable working power, the generator reliable disengaging electric during the assurance maintenance with net, assurance personnel's personal safety.
In addition, the generator in the foregoing description is preferably the small silent generator, generator can be placed on the outside like this, has reduced scope and difficulty that connection cable is laid.
In addition, in the generator powered loop, also be provided with start button.
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
