A protecting cover of the pressure-limiting device comprises, 20-30% of polytetrafluoroethene, 15-20% of nitrile butadiene rubber, 10-15% of FB resin, 5-10% of thermoplastic phenolic resin, 15-20% of epoxidized fatty acid methyl ester, 5-10% of diisooctyl phenyl phosphate, 5-10% of ferric oxide, 5-10% of zinc oxide, 1-7% of polyurethane and 2-8% of organic silicon. The sum of mass ratios of all the raw materials is 100%.
Description
Technical field
The present invention relates to electronic device field, relate to a kind of pressure limiting device with resistance toheat in particular.
Technical background
3 ~ 35kV power supply system superpotential phenomenon is very general, if do not have the precautionary measures, many cables all may occur at any time and blow out.These type of accidents such as electrical machine insulation punctures, PT burns, superpotential causes direct destruction to the circuit components in electric or electronic installation.This destruction, according to severity, can be divided into following several situation substantially: worked chaotic the equipment configuration short period of time: 1, to cause latent fault, the degradation making circuit and device, the lost of life, premature failure; 2, the permanent destruction of circuit and device is caused; 3, on fire, electric shock and other safety accidents is caused; 4, abnormal overvoltage may be external, also may be that equipment configuration is inner spontaneous.Its appearance may be regular, periodic, but be mostly random, therefore be in most cases difficult to hold it accurately.Single overvoltage protection measure is difficult to play effective preventive effect, and for this present situation, the multi-functional distribution of our company's development and production gathers excellent cabinet/overvoltage suppression cabinet.This device can effective various superpotential situation in detection system, and can effectively suppress.
And gather in excellent cabinet at multi-functional distribution, and having a requisite assembly---pressure limiting device, during existing pressure limiting device is produced, thermotolerance is poor, have impact on multi-functional distribution and gathers the quality that the use of excellent cabinet and multi-functional distribution gather excellent cabinet.
