Description
Technical field
It the utility model is related to a kind of portable pressure device for checking electric relay.
Background technology
Converter power transformer shunting switch pressure switch is to open and close the liquid electric switch of electrical contact letter using fluid pressure
Number conversion element.During setting pressure for reaching relay when system pressure, the action of electric signal control electrical equipment is sent,
Realize the protection of transformer.The converter power transformer shunting switch of ABB technology paths has all only matched somebody with somebody quick-action pressure switch,《Country
Grid company prevents DC converter station list 21 anti-accident measures of bipolar forced outage》In specifically mention the change of current become have load point
Connect switch and be only configured with oil stream or quick-action pressure switch is a kind of, tripping operation should be thrown.Once microswitch is positioned loosely or not had
There is compression, cause the change of operating valve value, along with the pressure in oil circuit is often what is fluctuated, when undulating value exceedes certain model
Enclose, cause pressure to arrive and, with regard to sender, cause converter power transformer tripping operation direct current to close also without signal output or also without to pressure
Lock either shunting switch internal fault pressure switch can not be acted correctly, all will bring potential safety hazard to grid equipment.
Pressure switch is the hydra-electric conversion element that electrical contact is opened and closed using the pressure of liquid.Work as system pressure
When reaching the setting of pressure switch, electric signal is sent, makes electrical equipment (such as electromagnet, motor, the time relay, electromagnetism
Clutch etc.) action, plays safeguard protection.It is arranged on transformer body fuel tank, shunting switch switching switch grease chamber is used for
Realize the protection to transformer.To ensure the safe and stable operation of power network, periodically pressure switch verified, analyze it
Whether working value is consistent with setting value.
At present because the cycle that standard criterion verifies to pressure switch does not have clear stipulaties, there is meter verification qualification
Unit is again without more preferable quick-action pressure switch calibration tool, the pressure switch malfunction of converter power transformer shunting switch configuration
Make that again direct current locking will be caused, repaiied less to avoid field apparatus from occurring, situation in bad repair, to ensure the normal fortune of power system
OK, there is pressure switch calibration tool easy to use, simple to operate, safe and reliable just to seem very at transformer station's O＆M scene
It is important.
Utility model content
The purpose of this utility model is to provide a kind of portable pressure relay easy to use, simple to operate, safe and reliable
Calibration equipment.
A kind of portable pressure device for checking electric relay, it is particular in that：Including triple valve, three of the triple valve
Connector connects precision pressure gauge, inflator and pressure switch respectively.
Three connectors of wherein triple valve are screw thread mouth.
Wherein two connectors of triple valve are respectively by being threaded the small hose of head and inflator and pressure switch
Connection.
The utility model device can be verified irregularly periodically or to pressure switch, fault diagnosis, analyze it
Can whether working value be consistent with setting value, action message.It has easy to use, simple in construction, safe and reliable, saving money
Source, can effectively realize live relay periodically or irregularly verification.The utility model device mainly by inflator (air pump),
Small hose, triple valve, the part of precision pressure gauge four composition, three connection screw thread mouths of triple valve connect respectively precision pressure gauge,
Inflator, pressure switch.The wherein small hose for connecting through suitable thread head of triple valve and inflator and pressure switch
Connection.Inflator can read pressure value during being pressurizeed to pressure switch on high-precision pressure gauge, so as to
Find out that can pressure switch correctly act, can be played an important role in equipment periodic inspection and fault diagnosis.This reality
With it is new have the advantages that it is easy to use, simple in construction, safe and reliable, economize on resources, can dive in time existing for discovering device
In problem.
Brief description of the drawings
Accompanying drawing 1 is structural representation of the present utility model.
Embodiment
As shown in figure 1, the utility model provides a kind of portable pressure device for checking electric relay, including triple valve 2, should
Three connectors of triple valve 2 connect precision pressure gauge 1, inflator 3 and testing pressure relay 4 respectively.Wherein triple valve 2
Three connectors are screw thread mouth, and two connectors of triple valve 2 are respectively by being threaded the small hose of head with inflating
Cylinder 3 and pressure switch 4 connect.
Application method and operation principle of the present utility model are：
Inflator 3 can read pressure value during being pressurizeed to pressure switch 4 on high-precision pressure gauge, so as to
It can be seen that can pressure switch 4 correctly act, so as to realize the regular or irregular verification to pressure switch 4.
