Abstract

The invention discloses an on-line IT system DC radio insulation detection device, which includes a filter circuit for filtering a DC input voltage and outputting a stable DC voltage; a chip for oscillating the stable DC voltage and outputting a high-frequency oscillation voltage; a single-chip MCU, Connect the chip and control the working mode of the chip; transformer, including primary side and secondary side; anti-peak absorption circuit; rectifier circuit; feedback circuit; indicator circuit; output circuit. The present invention reduces the probability of transformer primary side components being broken down through the anti-peak absorbing circuit, improves the safety of the device, and rectifies through the double diode series of the rectifier circuit, improves the voltage resistance of the rectifier, increases the service life of the device, and improves the service life of the device through the feedback circuit. Reduce signal impedance and improve signal response speed, increase the response speed of device detection, and the device can be directly connected to the line for online insulation detection, increasing the convenience of detection.

Description

technical field [0001] The invention relates to the field of safe electricity utilization, in particular to an on-line IT system DC radio insulation detection device. Background technique [0002] Production machinery and equipment need to run continuously when using electricity to improve production efficiency and reduce production costs. Long-term use of machinery and equipment is prone to insulation aging or insulation aging in the connected lines. In order to use electricity safely, mechanical equipment and Lines are regularly tested for insulation. [0003] Existing insulation detection devices are usually offline detection, that is, the detection needs to be performed after the mechanical equipment is powered off. However, for some factories, once the mechanical equipment stops running due to power failure, it will cause huge economic losses. Contents of the invention [0004] The object of the present invention is to solve the shortcoming of inability to perform on...
