Pressure cell, in use, in the case of high voltage, high current, it easily burns and produces naked light, thus burns out electricity
Road plate, or even damage whole equipment.In this regard, for protection equipment, just varistor must be encapsulated.In existing use
Varistor encapsulating structure, it is varistor to be fixed in housing using fluid sealant, and by piezoresistor
Two leads are drawn from the upper lid of housing, and it is sealing structure that it is internal.The varistor encapsulating structure of existing this kind of version
Its in use, when its internal varistor is subject to continuous high-pressure or thunderbolt destruction, it is possible to by the upper of housing
Lid is washed open and damaged.In view of this, for how searching out a kind of simple structure, working stability and can be prevented effectively from pressure-sensitive
The varistor encapsulating structure of resistance spontaneous combustion is just particularly important.
The content of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided a kind of simple structure, working stability and can
It is prevented effectively from the fire and explosion proof type piezoresistor encapsulating structure of varistor spontaneous combustion.
For achieving the above object, technical scheme provided by the utility model is:A kind of fire and explosion proof type piezoresistor
Encapsulating structure, the encapsulating structure includes varistor and the heat-resistant fireproof housing for installing the varistor, its
It is characterised by:Empty place between the varistor and heat-resistant fireproof housing is filled with possessing fire extinguishing and arc quenching effect is filled out
Fill thing.
Further, the fluid sealant for preventing the varistor from rocking is also filled with the encapsulating structure.
Further, the multiple perforates for discharging its interior heat energy are provided with described its bottom face of heat-resistant fireproof housing.
Preferably, the heat-resistant fireproof housing is made up of the end cap and base that are packaged in one, the varistor peace
In being mounted in the base intracavity, wherein being provided with the base its bottom face multiple for discharging produced by the varistor
The perforate of heat energy.
Further, the end cap is provided with for correcting two when varistor a pair of lead wires thereon is stretched out
The correction hole of mutual distance between person.
Yet further, its inner chamber of the base is provided with four locating pieces for installing the varistor.
Preferably, the implant is quartz sand.
Compared with prior art, by adopting said structure, it is this programme in failure can to cause varistor, has
Fire extinguishing and the implant of arc-suppression function(Such as quartz sand)The effect of fire extinguishing and arc extinguishing can be played, is just effectively avoided pressure-sensitive
The generation of the natural phenomena of resistance;The perforate that this shell body bottom offers can also effectively discharge partial heat energy, so as to can
Occur with the phenomenon for preventing housing from popping because of the big impact being subject to.
