Description
Technical field
The present invention relates to a kind of high-voltage switch gear, more particularly to a kind of simple in structure, reliability height, high pressures with long service life
Switch.
Background technology
The operation principle of pressure switch is：When system pressure is higher than specified safe pressure, disk wink in inductor
Shi Fasheng is moved, and is disconnected by connection guide pull switch connector, and when pressure is down to specified recovery value, disk wink resets,
Switch automatically resets, or is briefly when by measuring pressure overrate, and the free end of elastic element generates displacement, directly
It connects or pushes switch element after relatively, change the on off operating mode of switch element, achieve the purpose that control by measuring pressure.Pressure
Switch is the device being combined with electric switch, and when reaching preset Fluid pressure, make and break contact action is mainly answered
Output alarm or control signal, there is important use in industrial circle on the industrial equipments such as power plant, petrochemical industry, metallurgy industry
On the way, the damage that can prevent important device in production engineering occurs with avoiding great production accident.Pressure switch generally comprises machine
Tool formula, electronic type two major classes, mechanical pressure switches therein, which are purely mechanic deformation, causes microswitch to act, when pressure increases
When, it acts on different sensing pressure components (diaphragm, bellows, piston) and generates deformation, startup will be moved up topmost
Microswitch, make electric signal output.But it is usually one for triggering the triggering loose piece of microswitch in existing high-voltage switch gear
End is rotatably connected on valve body, and the other end is connected to by compressed spring elasticity on valve body, is pushed away when sensing pressure component deformation
Dynamic triggering loose piece rotation triggers microswitch upwards, since triggering loose piece uses the fixed rotation connection in one end, lifting
The inevitable microswitch contact relatively of process and sensing pressure component surface generate sliding, and the two stress is caused constantly to become
The surface abrasion changed, trigger sensitivity is made to decline, while being generated by friction, also reduces the service life of high-voltage switch gear.
