Box-type transformer high in safety and capable of achieving intelligent temperature control cooling

Abstract

The invention discloses a box-type transformer which is high in safety and capable of achieving intelligent temperature control cooling. The box-type transformer comprises a base, a transformer box and a cooling box; the transformer box is fixed on the base, the cooling box is fixed at the top end of the transformer box and provided with a first cooling fan and honeycomb-type cooling holes, the base is provided with cooling through holes and a second cooling fan, and fixed feet are installed on the four corners at the lower end of the base; the transformer box is internally provided with a central processing unit and a transformer which is provided with a temperature sensor, the temperature sensor is electrically connected with the central processing unit, and the central processing unit is connected with the first cooling fan and the second cooling fan through a driving module in a driving mode; the transformer box is further provided with an ampere meter, a current signal time domain processing device, a signal processing device and a vibrating sensor. The box-type transformer can ensure safe and stable operation of the box-type transformer, the anti-theft capacity is high, and normal work of a power system is guaranteed.

Description

technical field [0001] The invention relates to the field of electric equipment, in particular to a box-type transformer with high safety and intelligent temperature control and heat dissipation. Background technique [0002] In recent years, my country's electricity demand has grown rapidly, and the high-speed construction and investment of power grids have stimulated the market demand for power transmission and transformation equipment. Huge power construction funds have brought opportunities and challenges to the power transformer industry, which has promoted the rapid development of the transformer industry. Box-type substation, also known as prefabricated substation or prefabricated substation. It is a kind of high-voltage switchgear, distribution transformer and low-voltage power distribution device. It is a factory prefabricated indoor and outdoor compact power distribution equipment arranged according to a certain wiring scheme, which is about high-voltage power rec...

AI Technical Summary

Problems solved by technology

[0003] However, through the analysis of the operation status of box-type transformers in recent years, it is found that the number of failures each year accounts for a relatively large proportion of all failures of power distribution equipment, which seriously affects the health of the entire distribution network and the reliability of power supply for residents.

At present, during the operation of the box-type transformer, due to the high internal temperature, the insulation sheath on the copper bar is burned, the junction box of the secondary line is overheated and deformed, the metering CT is severely burned, and the terminals and meters are also caused by excessive temperature. But it cannot operate normally, and more seriously, the transformer cannot operate normally due to overheating and burnt out.

In addition, the existing box-type transformers are poor in anti-theft performance, and transformers are often stolen, and the frequency is increasing day by day, which will cause the transformers to fail to work normally, leading to large-scale power outages and other vicious accidents, which seriously affect people's normal life
