Prefabricated box-type transformer substation

Abstract

The invention relates to the technical field of transformer substations, in particular to a prefabricated box-type transformer substation which comprises a box-type transformer substation shell, a mounting base and a transformer; the transformer is arranged in the box-type transformer substation shell, the box-type transformer substation shell is fixed above the mounting base, and partition platesare arranged in the box-type transformer substation shell. The box-type transformer substation shell is divided into a low-voltage chamber, a high-voltage chamber and a transformer chamber by the partition plates, a voltage monitoring module, a current detection module, a temperature monitoring module, a 4G transmitting and remote control module and a controller are arranged in the high-voltage chamber, the low-voltage chamber and the transformer chamber, and an isolation screen is further arranged in the low-voltage chamber. And a power supply output terminal of the isolation screen is sequentially connected with a low-voltage incoming line intelligent circuit breaker and an intelligent power utilization controller in series. By means of the technical scheme, the working state of the transformer substation can be monitored in real time, and mutual switching between a common transformer substation and the transformer substation with the isolation function can be achieved.

Description

technical field [0001] The invention relates to the technical field of substations, in particular to a prefabricated box-type substation. Background technique [0002] Substations generally serve users within the radius of the area, but for field construction far away from substations, or industrial and mining enterprises, urban public buildings, or traffic construction units with relatively large power demand, directly using the power supply service of substations requires not only special Lines, and the cost of electricity is high, the risk of safe electricity use on site is high, and management and control are difficult. [0003] Therefore, the box-type substation came into being. The box-type substation can directly convert the voltage of 10KV into 0.4KV that can be used directly. It is very convenient to use, but when the box-type substation is working, the staff cannot know the temperature inside the transformer in real time. , voltage and other related parameters, so...

AI Technical Summary

Problems solved by technology

[0004] In view of the problems mentioned in the above background technology, the purpose of the present invention is to propose a prefabricated box-type substation to solve the problem that the traditional box-type substation cannot monitor its internal working status in real time, and cannot solve sudden problems. The problem of timely response, and the prefabricated box-type substation in remote areas cannot convert the low voltage of 0.4KV, nor can it output the ordinary low voltage and isolation voltage of 0.4KV at the same time, and there are certain problems in the demand for electricity.
