Peripheral protection device of unattended substation operation and maintenance station

Abstract

The invention discloses a peripheral protection device of an unattended power transformation operation and maintenance station in the field of protection devices, which comprises a power transformation box base, peripheral protective guards are arranged around the power transformation box base, long plates are arranged among the peripheral protective guards, a bent rod is arranged on one side surface of the top end of each long plate, and a supporting rod is arranged above the power transformation box base. An iron gauze is arranged between the two peripheral protective guards, a hollowed-out block is arranged on one side of each peripheral protective guard, a connecting plate is arranged in the middle of each hollowed-out block, a support is arranged at one end of each bent rod, a supporting rod is arranged at the top end of each support, and a rotating rod is arranged on the outer wall of one end of each supporting rod. According to the arrangement, splicing is convenient, the working intensity of workers is relieved, the protection range is wide, meanwhile, the rainproof and sunshade functions are achieved, the maintenance cost is reduced, the functions of the protection device are diversified, the transformer substation can be monitored, and warning reminding can be conducted on the workers or foreign personnel.

Description

technical field [0001] The invention belongs to the field of protective devices, in particular to a peripheral protective device of an unattended substation operation and maintenance station. Background technique [0002] Substation, a place where voltage is changed. In order to transmit the electric energy from the power plant to a distant place, the voltage must be raised to become high-voltage electricity, and the voltage must be lowered as needed near the user. The work of raising and lowering the voltage is done by the substation. The main equipment of a substation are switches and transformers. According to different sizes, the small ones are called substations. Substations are larger than substations. Substations generally refer to step-down substations with voltage levels below 110kV; substations include "boost and step-down" substations of various voltage levels. [0003] According to the patent application number CN202122952128.6, the peripheral protection devi...

Problems solved by technology

[0004] The purpose of the present invention is to provide a peripheral protection device for unattended power substation operation and maintenance station, so as to solve the problem that the peripheral protection device for unattended power substation operation and maintenance station proposed in the above background technology is not convenient for splicing, which increases the The working intensity of the staff is small, and the protection range is small. At the same time, it does not have the function of rain and sun shading, which increases the maintenance cost. Moreover, the function of the protection device is single, and the substation cannot be monitored, and there is also a lack of monitoring for the staff or outsiders. Alerting Questions
