Buried type transformer substation with emergency alarming device

Abstract

The invention relates to a buried type transformer substation with an emergency alarming device. The buried type transformer substation comprises a buried square pit located under the ground; the four sides and the bottom surface of the buried square pit all are concrete layers; a concrete cover is arranged above the buried square pit; the buried type transformer substation is characterized in that a water storage groove is downward formed in the bottom surface of one side of the buried square pit; a filtering screen is arranged above the water storage groove; a water pump is further arranged in the buried type transformer substation; a water inlet end of the water pump is communicated to the water storage groove through a pipeline; a water outlet end of the water pump is communicated with a water outlet of the concrete cover through a pipeline; the buried type transformer substation is internally further provided with a low liquid level sensor and a high liquid level sensor; the low liquid level sensor and the high liquid level sensor both are connected to a microcontroller; the microcontroller is connected with a first electromagnetic relay; the water pump is connected to a power supply through the first electromagnetic relay; the microcontroller is further connected with a GPRS (General Packet Radio Service) communication module.

Description

technical field [0001] The invention belongs to the technical field of electric power equipment, and relates to a buried substation, in particular to a buried substation with an emergency alarm device. Background technique [0002] Substation is an important part of power grid transmission, and plays a very important role in the transmission and distribution process of the entire power system; with the continuous development and progress of economic construction, the construction of substations has also increased sharply. Although the construction of substations meets the development of economic construction , but it will inevitably lead to the problem of increasing the land occupation area. [0003] In response to this problem, buried substations have appeared in the prior art, and the power equipment such as transformers and distribution cabinets are arranged below the bottom surface to reduce the land use area. [0004] However, the buried substation in the prior art has...

AI Technical Summary

Problems solved by technology

[0004] However, the buried substation in the prior art has the defect of difficult drainage of accumulated water, especially in the rainy season, the phenomenon of accumulated water is more serious; if the accumulated water in the substation cannot be discharged in time, it will have serious damage to the power equipment in the substation Potential safety hazards; in addition, the buried substation in the prior art does not have the function of real-time alarm, which leads to failure of timely maintenance when the substation fails
