Abstract

The present invention provides a constant voltage source. The constant voltage source comprises a housing which is internally provided with a circuit board, the circuit board is integrated with an alternating current input interface, the alternating current passes through the alternating current input interface and is connected with a rectification filtering circuit, a pulse width regulation power switch, an MOS bridge-type inversion circuit, an intermediate frequency high-voltage transformer, a voltage doubling regulation circuit and a high-voltage current-limiting resistor in order to output direct current high voltage through the direct current high-voltage output end; and the pulse width regulation power switch is connected with a controller through a feedback circuit, and the processor is electrically connected with an energy storage device, a temperature detection unit, an alarm unit, an illumination unit and an interface unit. The constant voltage source is low in design cost, small in wiring, rapid in production maintenance, high in efficiency, simple in structure, convenient to operate, high in accuracy and small in space usage.

Description

technical field [0001] The invention belongs to the field of electric equipment, and in particular relates to a voltage stabilizing source. Background technique [0002] Withstand voltage test refers to the test of the withstand voltage capability of various electrical devices, insulating materials and insulating structures. The process of applying a high voltage to an insulating material or insulating structure without destroying the performance of the insulating material is called a withstand voltage test. Generally speaking, the main purpose of the withstand voltage test is to check the ability of the insulation to withstand working voltage or overvoltage, and then to check whether the insulation performance of the product equipment meets the safety standards. [0003] The basic principle of the withstand voltage test: a voltage higher than the normal working voltage is applied to the insulator of the device under test, and lasts for a specified period of time. If the in...
