High-efficiency interception power-saving control circuit

Abstract

The invention provides a high-efficiency interception power-saving control circuit. The high-efficiency interception power-saving control circuit comprises a main power supply line and an interceptiontransformer. A primary coil of the interception transformer is connected with the output end of the main power supply line, and a secondary coil of the interception transformer comprises a welding machine power supply secondary coil and an electrical appliance power supply secondary coil. The welding machine power supply secondary coil is connected with a power supply line of a welding machine tobe connected, and the electrical appliance power supply secondary coil is connected with a power supply line of an electrical appliance to be connected. When the power supply line of the welding machine to be connected supplies power to the welding machine, the welding machine power supply secondary coil obtains the induced current from a primary coil, when the power supply line of the welding machine to be connected is disconnected from power supply of the welding machine; the electrical appliance power supply secondary coil obtains the induced current from the primary coil, and supplies power to the power supply line of the electrical appliance to be connected. The high-efficiency interception power-saving control circuit redesigns an existing electric welding machine working control circuit structure to solve the problem that an electric welding machine wastes power, and the configuration usage rate of the main control electric line is low during the static load standby process.

Description

technical field [0001] The invention relates to the technical field of electric welding machines, in particular to high-efficiency load interception and power-saving control circuits. Background technique [0002] The existing work control circuit structure of the electric welding machine mainly includes the main control electric circuit, the transformer and the power supply line of the electric welding machine connected in sequence. During the working process of the electric welding machine, it is supplied with power, but when the electric welding machine is not working, on the one hand, the transformer It is equivalent to no-load operation, which will lose a certain amount of current, resulting in waste of electric energy. On the other hand, the electric welding machine occupies the main control circuit and does not work during the idle process, resulting in a low configuration utilization rate of the main control circuit. Fully realize the existence value of the main cont...
