Magnetizing power source for magnetic defect detector

Abstract

The invention provides a magnetizing power source for a magnetic defect detector. The magnetizing power source for the magnetic defect detector comprises an entire chassis, and a charge circuit, a protection circuit, an electric quantity display circuit and a pulse removing circuit arranged in the entire chassis, wherein the charge circuit is connected with the protection circuit; the protection circuit is connected with the electric quantity display circuit; and the protection circuit is connected with the pulse removing circuit. The magnetizing power source for the magnetic defect detector provided by the invention has the beneficial effects of light weight, stable work, over-current protection in an output process, long service life, simplicity of maintenance, safety, reliability, and beautiful appearance.

Description

technical field [0001] The invention relates to a power supply, in particular to a stable, safe and reliable magnetized power supply for a magnetic particle flaw detector. Background technique [0002] At present, lead-acid maintenance-free batteries are generally used in the magnetization power supply for magnetic particle inspection in China. They are heavy in weight, small in capacity, short in use time, and inconvenient to maintain. To increase the use time, it is necessary to increase the weight and volume. [0003] The charging and discharging circuit of the power supply is unreasonable, resulting in problems such as short battery life and unstable operation. There is no protection circuit in the power supply, which cannot guarantee the safe use of the power supply, and has potential safety hazards. Contents of the invention [0004] The object of the present invention is to provide a magnetization power supply for a magnetic particle flaw detector, which has long se...

Problems solved by technology

[0002] At present, lead-acid maintenance-free batteries are generally used in domestic magnetic particle flaw detection magnetization power supplies, which are heavy in weight, small in capacity, short in use time, and inconvenient to maintain. To increase the use time, it is necessary to increase the weight and volume.

[0003] The charging and discharging circuit of the power supply is unreasonable, resulting in problems such as short battery life and unstable operation. There is no protection circuit in the power supply, which cannot guarantee the safety of the power supply, and has potential safety hazards.
