Automatic control device of electric welding machine

Abstract

The invention belongs to equipment for power transmission and transformation construction in the utility industry, and particularly relates to an automatic control device of an electric welding machine. The automatic control device comprises a power rectifying circuit (1) and an electric welding machine power circuit (2), and is characterized in that a control circuit (3) is further arranged in the device; and a voltage stabilization pipe U, a time relay SJ1, a triode Q, a normally-closed contact J, light emitting diodes D1 and D2, diodes D3 and D4, a voltage stabilization diode D5, an electrolytic capacitor C3, a capacitor C4, joints J1 and J2 and resistors R2-R7 are included in the control circuit. The device can control the power state of the electric welding machine in real time; whenthe electric welding machine stops welding work, the device can automatically cut off power, a motor is in a dormant state, no-load power consumption is reduced, and the power saving rate can reach 99% or above; when electric welding is needed, the device can automatically activate the electric welding machine, electric energy is saved, and the power factor of a power grid is increased; and duringthe interval of the electric welding machine, the temperature of the electric welding machine is reduced, copper losses are reduced, and the continuous welding capacity and work efficiency are improved.

Description

technical field [0001] The invention belongs to equipment for power transmission and transformation construction in the electric power industry, in particular to an automatic control device for an electric welding machine. Background technique [0002] At present, in the construction process of power transmission and transformation, the electric welding machine is one of the indispensable equipment. It consumes a lot of power in the production process. When the electric welding machine is welding, it often needs to do some other auxiliary ~ To help the work, the market will make the welding machine in the no-load state, which will waste a lot of electricity, cause a lot of reactive power loss to the enterprise power grid, and also bring safety hazards to the operators. Contents of the invention [0003] The purpose of the present invention is to overcome the above-mentioned technical deficiencies, and provide a safe and reliable automatic control device for electric weldin...
