Description

A removable branch box

technical field

The invention relates to electrical emergency equipment, in particular to a movable branch box.

Background technique

Box substations are often used in various electrical power distribution, and they have been used for a long time. Due to equipment aging and other reasons, they account for a certain proportion of daily emergency repairs. During the peak hours of electricity consumption caused by extreme weather, faults are prone to cause power outages for users, which greatly affects the safety and reliability of power supply, and has great hidden dangers to the operation of the distribution network. Therefore, a kind of emergency equipment is needed to improve the repair efficiency and reduce the power outage time of users.

Contents of the invention

The purpose of the present invention is to provide a movable branch box. The mobile branch box is exquisitely designed and connected with the low-voltage cable of the box transformer, so as to quickly restore the user's power supply, reduce the power outage time, and improve the repair efficiency.

In order to achieve the above object, the present invention is achieved through the following technical solutions:

A removable branch box is characterized by comprising:

box;

A pair of box doors, which are respectively arranged on both sides of the box body;

several rows of brackets, which are respectively horizontally arranged in the box;

The incoming busbar is arranged in the box and connected to the external generator car;

The circuit breaker component is fixed on the bracket, and the incoming line end is connected with the incoming line busbar.

The incoming busbars include phase A AC busbars, phase B AC busbars and phase C AC busbars.

The circuit breaker components are three circuit breakers, which are respectively connected to the A-phase AC busbar, the B-phase AC busbar and the C-phase AC busbar.

The branch box also includes several universal wheels, which are arranged at the bottom of the box body.

The connection between the box door and the box body is provided with a sealing strip.

Each outlet end of the circuit breaker is connected with an outlet cable, and the outlet cable is connected with the low-voltage cable of the box-type substation in failure.

Compared with the prior art, the present invention has the following advantages:

1. During the emergency repair process, the low-voltage cable of the box-type substation is removed from the hole brick and connected to the incoming busbar of the movable branch box to quickly restore the user's power supply, reduce power outage time, and improve emergency repair efficiency.

2. The present invention can move conveniently because universal wheels are provided at the bottom.

Detailed ways

The present invention will be further elaborated below by describing a preferred specific embodiment in detail in conjunction with the accompanying drawings.

As shown in Figures 1, 2, and 3, a movable branch box includes: a box body 1; a pair of box doors 2, which are respectively arranged on both sides of the box body 1; Inside the box body 1; the incoming line busbar is arranged in the box body and connected to the external generator car; the circuit breaker component is fixed on the bracket, and the incoming line terminal is connected to the incoming line busbar. The incoming busbars include an A-phase AC busbar 41 , a B-phase AC busbar 42 and a C-phase AC busbar 43 .

The circuit breaker components are three circuit breakers 5, which are respectively connected to the A-phase AC busbar 41, the B-phase AC busbar 42 and the C-phase AC busbar 43. The model of the circuit breaker 5 is Schneider NSX400N/3P.

The movable branch box also includes several universal wheels 6, which are arranged on the bottom of the box body 1. A sealing strip 21 is provided at the joint between the box door 2 and the box body 1 (see FIG. 4 ). Each outlet end of the circuit breaker is connected with an outlet cable 51, and the outlet cable 51 is connected with a faulty low-voltage cable of the box-type transformer.

Please refer to Fig. 3. In case of emergency in the present invention, the low-voltage cable of the box transformer is removed and led out from the hole brick, and connected with the outgoing cable 51. At the same time, the 3-phase wires of the external generator car are respectively connected to the A-phase AC busbar 41 and the B-phase The AC busbar 42 is connected to the C-phase AC busbar 43 . The 3-phase power of the generator car is transmitted to the 3 circuit breakers through the incoming busbar, and finally enters the low-voltage cable of the box transformer, so as to quickly restore the user's power supply.

To sum up, the present invention is a movable branch box, which is exquisitely designed and connected with the low-voltage cable of the box transformer, so as to quickly restore the user's power supply, reduce the power outage time, and improve the repair efficiency.

Although the content of the present invention has been described in detail through the above preferred embodiments, it should be understood that the above description should not be considered as limiting the present invention. Various modifications and alterations to the present invention will become apparent to those skilled in the art upon reading the above disclosure. Therefore, the protection scope of the present invention should be defined by the appended claims.
