Problems solved by technology

This device can be used to measure lightning impulse full wave and chopping wave voltage, operating impulse voltage and AC voltage, and can also be used as the basic load of impulse voltage generator. The patent number is CN201721428035.0 A high-voltage non-inductive impulse resistance divider The device can realize the above-mentioned functions of measuring lightning impulse full wave and chopping wave voltage, operating impulse voltage and AC voltage. The lightning impulse impulse resistance voltage divider that already exists in the market has the advantages of convenient use, firm structure, easy operation and maintenance. Simple and other advantages, can meet the requirements for measuring the lightning impulse full wave and chopping wave voltage, but for the existing lightning impulse impulse resistance voltage divider, on the one hand, in terms of transportation, it adopts an integral structure, which is not conducive to transportation. In terms of stability, the pressure equalizing ring structure is heavy, which makes the top of the equipment heavy, and is easy to be corroded by rain, easy to oxidize and rust, and has a large wind resistance, which is not conducive to the stability of the equipment. On the other hand, it cannot effectively The insulating ring is fixed. When using ropes to reinforce the supporting parts, the ropes are prone to looseness or excessive force, which cannot effectively maintain the fixing of the supporting parts. When measuring, due to the excessive voltage, it is easy to generate high heat. If it cannot be dissipated quickly, it is easy to affect the service life of the equipment, and it is not conducive to the measurement and use again
