A power cabinet airtight detection control system

Abstract

The invention discloses a power cabinet sealability detection control system. The system comprises a database, a wind pressure detection unit, a data analysis module, a locator, a monitoring center, adisplayer, a buzzer alarm, a main controller, a booster pump, an electromagnetic door stopper, an electric door closer, a control unit, an LED warning lamp and a memory, wherein the locator is fixedinside a power cabinet and is used for locating the power cabinet. According to the system, the booster pump blows air to the power cabinet in a normal state, and then wind pressure data is acquired through the wind pressure detection unit to create the database; and after a period of time, air is blown again through the booster pump, internal wind pressure is detected through the wind pressure detection unit, the detection result is compared with the database, and therefore a sealability result of the power cabinet is obtained. As a result, real-time detection of the sealability of the powercabinet is realized, and damage brought by poor air permeability or waterproofness of the power cabinet due to human negligence is avoided.

Description

technical field [0001] The invention relates to the technical field of power control systems, in particular to a power cabinet airtightness detection and control system. Background technique [0002] The stability of the power equipment inside the power cabinet will be affected by environmental factors such as humidity and temperature. Especially in southern my country, the air humidity is relatively high, especially in the rainy season and heavy wind and rain. If the equipment is operated in a highly humid environment for a long time, its insulation capacity will decrease, and its mechanical and electrical performance will be affected. In severe cases, it will discharge along the surface of the insulator, and even cause accidents such as malfunction and refusal to operate. [0003] During the use of the power cabinet, in order to ensure waterproof and air permeability, there are corresponding holes in the shell of the power cabinet, but these holes are not only breathable, b...

Problems solved by technology

[0002] The stability of the power equipment inside the power cabinet will be affected by environmental factors such as humidity and temperature. Especially in southern my country, the air humidity is relatively high, especially in the rainy season and heavy wind and rain. If the equipment is operated in a highly humid environment for a long time, its insulation capacity will decrease accordingly, and the mechanical and electrical properties will be affected. In severe cases, it will discharge along the surface of the insulator, and even cause accidents such as malfunction and refusal.

[0003] During the use of the power cabinet, in order to ensure waterproof and air permeability, there are corresponding holes in the shell of the power cabinet, but these holes are not only breathable, but also light-transmitting, which makes it easy for some phototaxis insects to pass through The hole enters the inside of the power cabinet, which causes the hole to be blocked and affects the air permeability. The usual rat bites and insects, control internal electrical components do not close the cabinet door in time, etc., will lead to changes in the sealing of the cabinet and affect the overall performance of the power cabinet. The airtightness reduces the waterproof performance of the power cabinet
