Problems solved by technology

When the controller circuit suddenly has a short-circuit fault, the excessive current may burn the controller circuit board to generate sparks or heat, cause combustion or explosion, and lose safety
Existing explosion-proof controllers all adopt the strategy of changing the circuit control in the controller, which not only reduces the scope of application of the product, but also increases the difficulty of production and increases the manufacturing cost

Abstract

The invention relates to an explosion-proof controller based on a mining motor. The explosion-proof controller comprises a controller integrated circuit, controller lead wires, and a combined type explosion-proof housing. The controller integrated circuit is arranged inside the combined type explosion-proof housing that is composed of an upper housing and a lower housing; space between the upper housing and the lower housing is filled with an insulated rubber and the upper housing and the lower housing are fixedly connected with an explosion-proof bolt; lead wire holes are arranged on the upper housing; the controller lead wires are connected with an external control circuit by the lead wire holes; and the lead wire holes are filled with sealing insulation rubbers. According to the invention, the explosion-proof controller has advantages of simple structure, low manufacturing cost, convenient installation, good explosion-proof performance, high security coefficient, and wide application range.

Description

technical field [0001] The invention relates to an explosion-proof controller based on a mining motor. Background technique [0002] Explosion-proof motors are widely used in flammable and explosive occasions such as petroleum, chemical and military industries. In these flammable and explosive dangerous places, conveying devices such as conveyor belts are sometimes used. Most of the driving motors are explosion-proof motors, and the controller that manipulates the motor becomes the key equipment. When the controller circuit suddenly has a short-circuit fault, the excessive current may burn the controller circuit board to generate sparks or heat, cause combustion or explosion, and lose safety. Existing explosion-proof controllers all adopt the strategy of changing the circuit control in the controller, which not only reduces the scope of application of the product, but also increases the difficulty of production and increases the manufacturing cost.
