Distribution substation intelligent distribution box

Abstract

The invention provides an intelligent distribution box of a distribution transformer, relates to intelligent power supply distribution management equipment, and aims at solving the problems that the connected point of a box body of an existing distribution box and external main power supply is arranged outside the box, so that the insulating sealing property is poor, and the box body is easily filled with water or affected with damp to oxidize, and is easy to age or overheat and the like, and the problems that the labor intensity of power constructors is increased during power-off maintenance and the like. The intelligent distribution box comprises an intelligent reset switch, an intelligent controller, a current relay protector, a control switch, a grounding protection device and a metering current transformer; the intelligent reset switch, the intelligent controller, the current relay protector, the control switch, the grounding protection device and the metering current transformer are fixed in the box body; the control switch is connected with the intelligent controller; the intelligent controller is connected with the intelligent reset switch; the intelligent reset switch is connected with the metering current transformer; the metering current transformer is connected with the current relay protector and an electric energy meter; and the intelligent reset switch is connected with the grounding protection device and load respectively. According to the intelligent distribution box, the main power supply can be automatically cut off by a distribution line in a power failure; and a three-phase short circuit of a load line is grounded, so that the safety of power supply maintenance personnel is ensured.

Description

technical field [0001] The invention relates to an intelligent power distribution management device, in particular to an intelligent distribution box for a power distribution substation. Background technique [0002] With the rapid development of power grid construction, large-scale construction and transformation of low-voltage power grids have also been carried out in recent years, including line insulation transformation, wire diameter increase, substation insulation, standardization, etc. Greatly improve the reliability of low-voltage power supply. However, it has been more than 10 years since the multi-functional distribution box of the transformer station was put into use, and it has not been upgraded, and there are the following safety and technical deficiencies. [0003] 1. With the rapid development of the economy, a large number of users (especially in the bustling business districts of urban areas) are irregularly using their own generators to generate electricit...

Problems solved by technology

[0005] The present invention solves the problem that the connection point between the box body of the existing distribution box and the external main power supply is located outside the box, resulting in poor insulation and sealing, easy water ingress or moisture oxidation, and aging and overheating problems, and there is an on-site emergency response during power failure maintenance. The maintenance personnel cannot judge the problem points according to the current on-site conditions, which will increase the labor intensity of the electric construction personnel and other problems, and provide an intelligent distribution box for power distribution substations
