Abstract
The embodiment of the utility model provides a non-power-off device, which is fixedly arranged on a control screen of a substation control room. A generator is inserted in a socket of the device, and two substation transformer normally closed contacts are in series connection with a generator power supply return circuit. When the substation transformer is in a normal working state, the two substation transformer normally closed contacts are opened, and when the substation transformer is in a breakdown state, the two substation transformer normally closed contacts are closed. The non-power-off device can ensure that when two substations are powered off simultaneously, a power supply in the non-power-off device becomes the only reliable working power supply, ensures reliable release of the generator and a network power supply during overhaul, and guarantees personal safety of the staff.
Description
Technical field
The utility model belongs to the power technology field, relates in particular to a kind of fool proof device that do not have a power failure of electric substation that is used for.
Background technology
It is of crucial importance that electric substation anti-delayed work; Power failure perhaps loses 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 special working power be provided maintenance department 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.
The utility model content
In view of this, the purpose of the utility model is to provide a kind of device that do not have a power failure, and can improve the personal security of maintenance.
For realizing above-mentioned purpose; An embodiment of the utility model provides a kind of device that do not have a power failure; This device is used for electric substation's anti-misoperation; This device is fixedly mounted on the control flow in electric substation control room, on the socket of this device, is inserted with generator, be in series with on the said 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 to become normally closed contact closed.
Preferably, this device is connected with said control flow through the cable trough payout.
Preferably, said generator is the small silent generator.
Preferably, also be provided with start button in the said generator powered loop.
The device that do not have a power failure among the utility model embodiment only can guarantee two become under the situation that does not have electricity simultaneously; The power supply that does not have a power failure in the device becomes unique reliable work power supply; The generator reliable disengaging electric when guaranteeing to overhaul with net, assurance personnel's personal safety.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment 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; Obviously, the accompanying drawing in describing below is some embodiment of the utility model, 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 electrical schematic diagram of an embodiment of the device that do not have a power failure that provides of the utility model.
Embodiment
For the purpose, technical scheme and the advantage that make the utility model embodiment clearer; To combine the accompanying drawing among the utility model embodiment below; Technical scheme among the utility model embodiment is carried out clear, intactly description; Obviously, described embodiment is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
Fig. 1 shows the electrical schematic diagram of an embodiment of the device that do not have a power failure that the utility model provides.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 the electrical interlock of its casing and used electric screen two road incoming powers is inserted with generator on the socket of this device.。
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 work power supply; The generator reliable disengaging electric during the assurance maintenance with net, assurance personnel's personal safety.
In addition, in a preferred embodiment of the utility model, the above-mentioned device that do not have a power failure is put control cable through cable trough and is connected with the control flow in control room,
Like this, the device that do not have a power failure of the utility model can once mounting be accomplished, and only need generator be inserted in the socket of device in use to get final product, and is very easy to the overlap joint of generator cable.
In addition, the generator in the foregoing description is preferably the small silent generator, can generator 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 the preferred implementation of the utility model; Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; Can also make some improvement and retouching, these improvement and retouching also should be regarded as the protection range of the utility model.
Claims (4)
1. the device that do not have a power failure is used for electric substation's anti-misoperation, it is characterized in that, this device is fixedly mounted on the control flow in electric substation control room, on the socket of this device, is inserted with generator, be in series with on the said 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 to become normally closed contact closed.
2. based on the described device that do not have a power failure of claim 1, it is characterized in that this device is connected with said control flow through the cable duct payout.
