Problems solved by technology
[0002] At present, the demolition equipment on the market has manual, hydraulic, motorized and chemical cutting types; for hydraulic rescue equipment, hydraulic power is used to provide power to disassemble the equipment to be dismantled, and the disassembly is slow; because the hydraulic pliers of hydraulic rescue equipment have a certain width, For some devices to be demolished with small gaps, it is difficult to achieve demolition
For chemical cutting and demolition equipment, high-frequency arc ignition is used, but the output of high frequency requires high high voltage for arc ignition. High voltage will cause great damage to human body and equipment; When the high-altitude or far-away rescue device is to be demolished, due to the large attenuation of high frequency, the longer the cable, the more difficult it is to strike the arc

The invention discloses a rapid rescue device and a low-frequency arc starting method thereof. The rapid rescue device includes a rescue gun head and a control circuit connected to the rescue gun head; the rescue gun head is connected to an air compressor through a high-pressure air pipe; The input rectification circuit rectifies the power frequency alternating current into direct current, which is converted into high-voltage and high-frequency alternating current by the IGBT inverter circuit after filtering, and then converted into low-voltage and high-frequency alternating current through the transformer, and then rectified into direct current by the output rectifying circuit to supply the demolition gun.
Description
technical field [0001] The invention belongs to the technical field of firefighting and rescue, and in particular relates to a rapid rescue device and a low-frequency arc starting method thereof. Background technique [0002] At present, the demolition equipment on the market has manual, hydraulic, motorized and chemical cutting types; for hydraulic rescue equipment, hydraulic power is used to provide power to disassemble the equipment to be dismantled, and the disassembly is slow; because the hydraulic pliers of hydraulic rescue equipment have a certain width, It is difficult to realize the demolition for some devices to be demolished with smaller gaps. For chemical cutting and demolition equipment, high-frequency arc ignition is used, but the output of high frequency requires high high voltage for arc ignition. High voltage will cause great damage to human body and equipment; When the high-altitude or far-away rescue device is to be demolished, due to the large attenuatio...
