Flame-retardant AC frequency converter explosion-proof box with anti-pollution function

Abstract

The invention discloses a flame-retardant AC frequency converter explosion-proof box with an anti-pollution function, and the box comprises a box body, a fixed plate is disposed in the box body, a frequency converter is disposed on the fixed plate, and the upper end surface of the fixed plate is provided with a first groove. The frequency converter is reasonable in structure, noise generated whenthe frequency converter works is effectively controlled through a silencing mechanism, noise pollution is avoided, vibration of the frequency converter is reduced through a damping mechanism when thefrequency converter works, damage, caused by vibration, to the frequency converter and influence on the working efficiency are avoided, and meanwhile the service life of the frequency converter is prolonged; by arranging a triggering mechanism, the frequency converter can be quickly extinguished and cooled when continuously working and accidentally catching a fire, fire disasters and resource losses are avoided, and by arranging a clamping mechanism, a silencing plate can be conveniently disassembled and assembled, and the situation that the working efficiency is low due to a tedious replacement process is avoided.

Description

technical field [0001] The invention relates to the technical field of AC frequency converter protection, in particular to a flame-retardant type AC frequency converter explosion-proof box with anti-pollution function. Background technique [0002] AC frequency converter is a speed control device with adjustable output voltage and frequency. AC frequency converter is actually an inverter. It first converts AC power into DC power, and then uses electronic components to switch DC power into AC power. Larger AC frequency converters use silicon controlled rectifiers, and set up an adjustable frequency device to make the frequency adjustable within a certain range, which is used to control the number of revolutions of the motor so that the number of revolutions can be adjusted within a certain range. Inverters are used in flammable and explosive places such as mines and flour mills, and the application of AC inverter explosion-proof boxes is becoming more and more extensive. Ther...

Problems solved by technology

[0003] The existing AC frequency converter explosion-proof box is to place the frequency converter in a box made of iron plates, but vibration and noise will be generated when the frequency converter is running, causing noise pollution. At the same time, the existing AC frequency converter explosion-proof box is When the frequency converter burns out, it needs to be extinguished manually, and the explosion-proof box needs to be opened when extinguishing the fire, but this method of extinguishing the fire is slow

It is easy to cause the fire because it cannot be controlled quickly and effectively, thus causing potential safety hazards
