Problems solved by technology

[0002] At present, the output terminal and the intermediate barge interface of the emergency generator car generally adopt the method of quick barge connection, and the barge time is only 1 to 2 minutes, which is about 20 to 30 minutes faster than the traditional line lug barge, which greatly shortens the time after power failure. When it is time for emergency power supply, the efficiency of rapid power restoration is improved. In the prior art, the power distribution equipment of the bench-type transformer at the user end only adopts the traditional wire lug connection method, which has a long working time and hinders rapid power restoration. At the same time , there is no fixed emergency power access point, it is easy to cause misoperation, resulting in the phenomenon of reverse power supply

Embodiment 1

[0030] Example 1: For 100~250kVA integrated distribution box

[0031] When the mains power fails, disconnect the feeder switch 12, disconnect the main switch 11, push the double-throwing knife switch 5 to the generator terminal 3, open the movable small door 9, connect the generator car with the quick wiring insert 10, and the generator car starts Then close the main switch 11, and then close the feeder switch 12; when the mains power is restored, stop the generator car to generate electricity, disconnect the feeder switch 12, disconnect the main switch 11, and push the double-throwing knife switch 5 to the mains terminal 1. Turn on the main switch 11, turn on the feeder switch 12, and close the movable door 9.

Embodiment 2

[0032] Example 2: For 315~500kVA integrated distribution box

[0033] When the mains power fails, disconnect the feeder switch 11, then disconnect the main switch 12, push the double-throwing knife switch 5 to the generator terminal 3, open the movable small door 9, connect the generator car quick connector 8, and the generator car starts Then close the main switch 11, close the feeder switch 12 to supply power to the load; when the mains is restored, stop the generator car to generate electricity, disconnect the feeder switch 12, turn off the main switch 11, and push the double-throwing knife switch 5 to the mains Terminal 1, pull out quick connector 8, close main switch 11, close feeder switch 12, close movable small door 9.

Abstract

The invention belongs to the field of power distribution devices and relates to a power distribution device having an emergency quick power restoration function. The power distribution device comprises a box, a commercial power wiring terminal, a user wiring terminal, and a power generation wiring terminal, wherein the commercial wiring terminal and the user wiring terminal are arranged in the box and are connected to each other via a single-pole switch, the power generation wiring terminal is provided with a quick binding post, the commercial power wiring terminal and the user wiring terminal are connected to each other via a double-pole switch, one end of the double-pole switch is fixedly connected with the user wiring terminal, and the other end of the double-pole switch is connected with the commercial power wiring terminal or the power generation wiring terminal. According to the power distribution device having the emergency quick power restoration function, when a commercial power supply terminal cannot supply power to users normally, power can be supplied to the users within shortest time just by achieving fast connection by connecting the double-pole switch to the power generation wiring terminal to be connected to a power generation vehicle via the quick binding post. Further, the power distribution device also has a function of preventing reverse power supply.

Description

technical field [0001] The invention belongs to the field of power distribution devices, and more specifically relates to a power distribution device with an emergency quick power restoration function. Background technique [0002] At present, the output terminal and the intermediate barge interface of the emergency generator car generally adopt the method of quick barge connection, and the barge time is only 1 to 2 minutes, which is about 20 to 30 minutes faster than the traditional line lug barge, which greatly shortens the time after power failure. When it is time for emergency power supply, the efficiency of rapid power restoration is improved. In the prior art, the power distribution equipment of the bench-type transformer at the user end only adopts the traditional wire lug connection method, which has a long working time and hinders rapid power restoration. At the same time , There is no fixed emergency power access point, which is prone to misoperation and cause reve...
