Problems solved by technology

Moreover, in order to ensure that when the emergency power supply is powered, the low voltage will not send power backwards to the transformer side to cause safety hazards. The existing emergency power supply scheme adopts the method of disconnecting the busbar and blocking the emergency power supply interface in the form of a baffle when it does not need to be plugged in. , to ensure that the emergency power supply interface is not exposed during normal power supply. However, when the emergency power supply needs to be used, it is necessary to manually disassemble the emergency power supply busbar to expose the emergency power supply interface before connecting the power supply. Undoubtedly, it takes a certain amount of work to remove the emergency power supply busbar. time

Abstract

The invention discloses an emergency power supply device for a box-type substation. The emergency power supply device comprises an emergency power supply, a dual power supply changeover switch and a handle assembly. The outgoing end of the dual power supply changeover switch is electrically connected with a low voltage shunt switch. The handle assembly is used for controlling the incoming end of the dual power supply changeover switch to switch on the emergency power supply or the transformer, When the emergency power supply is needed for power supply, the incoming end of the dual power supplychangeover switch is enabled to be connected with the emergency power supply by the handle assembly so that the emergency power supply can be quickly realized and the power failure time on the user side can be greatly shortened.

Description

technical field [0001] The invention relates to the technical field of electrical engineering, in particular to an emergency power supply device for a box-type substation. Background technique [0002] Box-type transformer (referred to as box-type transformer) is a kind of high-voltage switchgear, distribution transformer and low-voltage power distribution device arranged according to a certain wiring scheme, which is a factory prefabricated indoor and outdoor compact power distribution equipment. The box substation has the advantages of high degree of automation, factory prefabrication, flexible combination, and small footprint, so it is widely used in residential quarters, public facilities, construction sites, etc. However, in actual use, box-type transformers often experience power outages due to line maintenance, line faults, component damage, etc., which brings economic losses and inconvenience to users. [0003] At present, in order to reduce the power-off time on th...
