Embodiment 1

[0033] figure 1 A schematic structural diagram of the distribution box provided by Embodiment 1 of the present invention is shown, figure 2 A schematic diagram of the door structure of the distribution box provided in Embodiment 1 of the present invention is shown; the distribution box provided in this embodiment includes a box body 1 and a box door 24, the box body 1 and the box door 24 are hinged, and the box The door 24 is provided with a door lock 25 to provide protection for the equipment in the box body 1 .

[0034] In the distribution box provided by Embodiment 1 of the present invention, the box body 1 includes a multi-circuit control terminal 3, a main branch circuit breaker 8, a backup branch circuit breaker 9, a main branch current transformer 10, a backup branch current Transformer 11, main branch contactor 12, backup branch contactor 13, power module 14; the incoming line of the box 1 is divided into at least two branches, the main branch and the backup branch, ...

Embodiment 2

[0052] Figure 5 It shows a schematic structural diagram of the distribution box provided by Embodiment 2 of the present invention. The parts that are the same as those in Embodiment 1 use the same reference numerals. Only the differences will be described below. A distribution box provided by Embodiment 2 of the present invention For the electrical box, when the number of external input / output interfaces does not exceed the number of input / output interfaces configured by the multi-loop control terminal 3, the expansion module 4 may not be used, and the connections related to the expansion module 4 are correspondingly reduced, thereby reducing production costs.

Embodiment 3

[0054] Figure 6 It shows the schematic structural diagram of the distribution box provided by the third embodiment of the present invention, and the same parts as the first embodiment use the same reference numerals, and only the differences will be described below. A distribution box provided by the third embodiment of the present invention For the electric box, when the user does not have local and remote monitoring and control function requirements, the display terminal 15 may not be used, and the connections related to the display terminal 15 are correspondingly reduced, thereby reducing the production cost.

Abstract

The invention relates to a distribution box. The distribution box comprises a box body and a box door, and the box body is hinged with the box door; and the box body comprises a multi-loop control terminal, a main branch circuit breaker, a standby branch circuit breaker, a main branch current transformer, a standby branch current transformer, a main branch contactor, a standby branch contactor anda power supply module; the incoming line of the box body is divided into at least two branch circuits, namely a main branch circuit and a standby branch circuit, so that the reliability of the distribution box is improved. According to the invention, local and remote protection, control, monitoring and management of all parts of the distribution box can be realized, intelligent control and faultalarm can be carried out on the power distribution system, and a manual operation display unit is added, so that the safety of the distribution box is improved, the power distribution box is convenient to maintain, all parts of the power distribution box are high in structural modularization degree, the distribution box is good in safety, high in reliability, high in integration degree and intelligent degree and convenient to assemble, maintain, monitor and control, better controllability and expandability are achieved, and the increasingly high power distribution and power control requirements of users can be met.

Description

technical field [0001] The invention belongs to the technical field of power distribution equipment, and relates to a power distribution box. Background technique [0002] The power distribution box is an important part of power management and electrical control, especially the traditional power distribution box. Usually, circuit breakers, current transformers, contactors, fuses and other equipment are simply placed in the power distribution box. When It can be satisfied when the user's demand for power distribution is low, but at present, with the increasing demand for power distribution of users, some electrical equipment requires the power distribution system to have high reliability and the ability to diagnose faults in advance, while the traditional distribution box Faced with the problem that the user's demand for power distribution is high, it can no longer be satisfied, and it is not suitable for intelligent control of power distribution on-off; Poor performance, lo...
