Safety protection device for power system

Abstract

The invention discloses a safety protection device for a power system in the technical field of power system protection. The device comprises a protection box body, wherein transparent tempered glass plates are embedded and fixedly installed above the left and right sides of the protection box body through through grooves, and the left and right sides of the bottom of the protection box body are fixedly provided with equal-height channel steel sections and vertical plates in an equal-width manner; a box cover with a sealing rubber ring is hinged to the top of the protection box body, when a temperature signal sensed by the temperature sensor exceeds a set threshold value of the controller, the two electric gates and the first air suction fan are opened to complete heat dissipation, and when a humidity signal sensed by the humidity sensor exceeds the set threshold value of the controller, the semiconductor chilling plate and the second air suction fan work; air flow in the protection box body flows, moisture in the air is separated out through refrigeration and discharged, the humidity is reduced, if the humidity and the temperature trigger the controller to work, the humidity and the temperature are matched, wiring knotting can be prevented, operation is convenient, and the automation degree is high.

Description

technical field [0001] The invention relates to the technical field of power system protection, in particular to a safety protection device for a power system. Background technique [0002] The power system is an electric energy production and consumption system composed of power plants, power transmission and transformation lines, power supply and distribution stations, and power consumption. Its function is to convert the primary energy in nature into electric energy through the power generation device, and then supply the electric energy to various users through power transmission, transformation and distribution. In order to realize this function, the power system also has corresponding information and control systems in various links and different levels to measure, adjust, control, protect, communicate and dispatch the production process of electric energy, so as to ensure that users obtain safe and high-quality electric energy. . [0003] The main structure of the p...

Problems solved by technology

The structure of the power system should ensure the reasonable coordination of electric energy production and consumption on the basis of advanced technical equipment and high economic benefits. The most critical factor for the normal operation and transmission of electric power in the power plant is the electrical equipment, but the existing The equipment of the current power system does not have safety protection devices, and the existing power system equipment does not have the function of binding wires, resulting in knotted connecting wires, which is inconvenient for maintenance, and the existing heat dissipation function is not good, and it is easy to be damp in rainy weather, affecting For example, CN210957503U discloses a safety protection device for electrical power system equipment, including a protective cover body, a first motor and a second motor, the left side of the protective cover body is inserted with a first air duct, and A filter frame is fixedly installed at the outlet of the inner bottom end of the first air duct, and a fan is installed inside the filter frame through a bearing seat

This solution is provided with the first air duct, and the heat flow is blown to the outside of the right side of the protective cover body through the rotation of the fan, so that the moisture from the bottom of the protective cover body can be removed from the outside of the protective cover body in humid weather, and it can prevent moisture. The first filter is damaged by moisture. The device is equipped with an axial fan to prevent the first filter from being damaged due to high internal temperature of the protective cover body, which will affect the use. Through the contraction force of the spring itself, it is convenient to clamp multiple sets of connecting wires, which is convenient. Bundle the wires to prevent the connecting wires from knotting, which is inconvenient for maintenance, but the device cannot be intelligently controlled, which brings inconvenience to use. Based on this, the present invention designs a safety protection device for power systems to solve the above problems
