Abstract
The utility model relates to voltage switchgear Power transfer system, comprise the voltage switchgear be made up of at least two switch cubicles, input power and service entrance switch is equipped with in each switch cubicle, it also comprises the relay for switching input power, and described input power is connected with service entrance switch by relay.This voltage switchgear can also normally work when the service entrance switch of this cabinet after one of them switch cubicle power-off.
Description
Technical field
The utility model relates to switch cubicle technical field, particularly relates to voltage switchgear Power transfer system.
Background technology
Voltage switchgear generally comprises multiple switch cubicle, each switch cubicle includes input power and service entrance switch, prior art service entrance switch operating power generally takes from this cabinet input power, and service entrance switch is not generally with no-voltage trip to protect, so when one of them switch cubicle input power breaks down, the service entrance switch of this switch cubicle cannot can disconnect automatically because operating power disappears, operating personnel are now just needed manually to go to disconnect the operation of service entrance switch, operate so not very convenient, and the indicator light of this service entrance switch also cannot show because not having power supply simultaneously, easily there is blind area, namely make the operation disconnecting service entrance switch more inconvenient like this.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of voltage switchgear Power transfer system that can also normally work when the service entrance switch of this cabinet after one of them switch cubicle power-off.
The technical scheme that the utility model adopts is: a kind of voltage switchgear Power transfer system, comprise the voltage switchgear be made up of at least two each and every one switch cubicles, input power and service entrance switch is equipped with in each switch cubicle, it also comprises the relay for switching input power, and described input power is connected with service entrance switch by relay.
Adopt above structure compared with prior art, the utility model has the following advantages: arrange like this, as long as be normal when there being a switch cubicle to be input power in voltage switchgear, service entrance switch in then all switch cubicles all can normal power-up normally work, such control is fairly simple, makes practical operation convenient.
As preferably, described input power to be connected with service entrance switch by relay and to refer to, described voltage switchgear comprises two switch cubicles, be respectively the first switch cubicle and second switch cabinet, described first switch cubicle comprises the first input power and the first service entrance switch, second switch cabinet comprises the second input power and the second service entrance switch, the coil of described relay is connected with the first input power, and described first input power is connected with the normally opened contact of relay, described second input power is connected with the normally-closed contact of relay, described first service entrance switch is all connected with the common of relay with the second service entrance switch.Such setting, when the first input power is normal, then relay coil obtains electric work, normally-closed contact disconnects, normally opened contact closes, and namely the first service entrance switch and the second service entrance switch are all communicated with the first input power, and the first service entrance switch and the second service entrance switch all can normally be worked; When the first input power breaks down, when second input power normally works, relay coil not electric, normally-closed contact is then kept to close, normally opened contact disconnects, then now the first service entrance switch and the second service entrance switch are all connected with the second input power, the first service entrance switch and the second service entrance switch still normally can be worked, can ensure the normal work of multiple service entrance switch like this.
Accompanying drawing explanation
Fig. 1 is the connection block diagram of the utility model voltage switchgear Power transfer system.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is described further, but the utility model is not limited only to following embodiment.
As shown in the figure: a kind of voltage switchgear Power transfer system, comprise the voltage switchgear be made up of at least two each and every one switch cubicles, input power and service entrance switch is equipped with in each switch cubicle, it also comprises the relay for switching input power, and described input power is connected with service entrance switch by relay.
Described input power to be connected with service entrance switch by relay and to refer to, described voltage switchgear comprises two switch cubicles, be respectively the first switch cubicle and second switch cabinet, described first switch cubicle comprises the first input power and the first service entrance switch, second switch cabinet comprises the second input power and the second service entrance switch, the coil of described relay is connected with the first input power, and described first input power is connected with the normally opened contact of relay, described second input power is connected with the normally-closed contact of relay, described first service entrance switch is all connected with the common of relay with the second service entrance switch.Described first service entrance switch and the second service entrance switch are circuit breaker, and described relay is connected with the power module of circuit breaker.
The operation principle of the application is: when the first input power normally works, and the first service entrance switch and the second service entrance switch are all be communicated with the first input power, keeps energising normal operating conditions; When the first input power breaks down, relay will carry out electrical source exchange, first service entrance switch is communicated with the second input power with the second service entrance switch, make the first service entrance switch and the second service entrance switch still can keep the normal operating conditions that is energized, so just do not need operating personnel manually to go to control.
