Intelligent explosion-proof controller

Abstract

The invention discloses an intelligent explosion-proof controller including a lower explosion-proof house, a control panel and a display panel are arranged on the lower explosion-proof shell, the control panel is located on the right side of the display panel, a control button is arranged on the control panel, an instrument window and a display lamp are arranged on the display panel, the instrument window is located at the top of the display lamp, the lower explosion-proof shell is fixedly connected with the upper explosion-proof shell through a nut, the inside of the upper explosion-proof shell is provided with a circuit breaker and an instrument, the circuit breaker is located on the right side of the instrument and is electrically connected with the instrument, and the inside of the circuit breaker is provided with a sensing unit. According to the intelligent explosion-proof controller of the invention, by the setting of the upper explosion-proof shell and the lower explosion-proofshell, the damage of the external environment to the internal structure of the shell is effectively protected, and the threat to the external personnel is effectively avoided when the controller failsto explode internally. By setting the sensing unit, the controller is detected, so that people can easily understand the internal situation of the controller.

Description

technical field [0001] The invention relates to the technical field of controllers, in particular to an intelligent explosion-proof controller. Background technique [0002] Explosion-proof refers to the prevention of explosions. To prevent explosions, three necessary conditions must be considered. Limiting one of the necessary conditions limits the occurrence of explosions. The motor refers to an electromagnetic device that realizes electric energy conversion or transmission according to the law of electromagnetic induction. , represented by the letter M in the circuit, its main function is to generate driving torque, as a power source for electrical appliances or various machinery, in the conveyor belt handling device, most of the driving power is the motor, and the controller that manipulates the motor Then it becomes the key equipment. The controller refers to the main command device that changes the wiring of the main circuit or the control circuit and changes the resis...

[0002] Explosion-proof refers to the prevention of explosions. To prevent explosions, three necessary conditions must be considered. Limiting one of the necessary conditions limits the occurrence of explosions. The motor refers to an electromagnetic device that realizes electric energy conversion or transmission according to the law of electromagnetic induction. , represented by the letter M in the circuit, its main function is to generate driving torque, as a power source for electrical appliances or various machinery, in the conveyor belt handling device, most of the driving power is the motor, and the controller that manipulates the motor Then it becomes the key equipment. The controller refers to the main command device that changes the wiring of the main circuit or the control circuit and changes the resistance value in the circuit to control the starting, speed regulation, braking and reverse of the motor in a predetermined order. When a short-circuit fault occurs suddenly in the circuit of the controller, the excessive current may burn out the circuit board of the controller, thereby generating sparks or heating, causing combustion or explosion, and the safety is low
