Description
Technical field
The utility model belongs to electric power overhaul field, relates to a kind of air pressure switch debugging apparatus.
Background technology
The effect of air system pressure switch is to provide equipment and is in operation the action and reset signal that keep pressure, provides the major parameter of the operating space scope of each signal, the supplemental characteristic that pressure switch three kinds of can show when action are different; Main distribution is: (1), compressor Pneumatic pressure force value 1.45Mpa---1.55Mpa: when compressor pressure falls in 1.45Mpa, start compressor starts to suppress, beat and stop to during 1.55Mpa, working value and reset values gauge pressure are one and limit gauge pressure, do not fall in 2Mpa in 24 hours of regulation; (2), reclosing Pneumatic pressure force value 1.44Mpa---1.46Mpa: the compressor start when air pressure is fallen in 1.44MPpa, beat to during 1.46Mpa pressure stop; Working value and reset values gauge pressure are 0.3 ± 1 limit gauge pressure (3), locking force value 1.2Mpa---1.3Mpa: signalizing activity value: the compressor start when Pressure Drop is in 1.2Mpa, beat and automatically terminate abnormal signal to during 1.3Mpa, when lower than 1.2Mpa pressure, the action of signal automatic blocking primary cut-out, formation infrabar is reported to the police, and forbids equipment operating; Working value and reset values gauge pressure are one and limit gauge pressure, to effective early warning of the safe operation of primary cut-out and detection means when above-mentioned three kinds of different signal value reflection pressure change the signal sent, guarantee the secure safety that primary cut-out runs.
Conventional air pressure switch 63AG, 63AR, 63AL action is unstable, causes primarily of following reason:
Reason (one) air pressure switch actuating signal has drift, and reset signal and main signal are not corresponding;
Unstable and the microswitch of reason (two) valve capacity size and spring action under different force value year in year out, make the elegant instability of its spring action, cause reset signal and main signal not corresponding;
Reason (three) switch motion and compressor start, make its pipeline and valve input tolerance size instability, cause caging bolt to loosen, cause signal elegant and unstable;
Reason (four) debug its pressure switch in working site, due to the hinge power station that 330kV electric pressure switch is country's allotment, there are power-on time and method of operation restriction, therefore, field adjustable is subject to time and manual operation and psychological pressure impact, in order to the power supply that races against time, cause tune-up data inaccurate.
The debugging of current air pressure switch all will be carried out at the scene, to be suppressed to air switch by air pump and test, period will stop power supply, repeatedly carry out debugging efforts, this check and correction detection method work length consuming time, affect electrical network normal power supply, and in order to shorten power off time, cause tune-up data often inaccurate.
Utility model content
The purpose of this utility model is to overcome prior art defect, provides a kind of air pressure switch debugging apparatus, effectively increases work efficiency, and guarantees that the stability of air system is run.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of air pressure switch debugging apparatus, comprise connecting tube, connecting tube is connected with the air pump be communicated with it, connecting tube is also connected with the multiple branches pipeline be communicated with it respectively, each branch line is installed respectively air manometer, vent valve and pressure switch to be debugged, reverse checkvalve and single exhaust valve are also installed between each branch line and connecting tube; Between air pump and multichannel arm, throttling valve is installed, air pump is provided with the gas handle controlling air pump work, adapter road is also provided with gas input pressure table.
Described connecting tube is also connected with nitrogen gas cylinder, air pump and install throttling valve between nitrogen gas cylinder and multichannel arm.
Described connecting tube is connected with five road branch lines, each branch line is installed respectively air manometer, the first pressure switch, the second pressure switch, the 3rd pressure switch and the debugging vent valve for relief pressure.
The orifice diameter of described throttling valve is
φ0.5mm.
Described air pump is provided with the tensimeter for showing air pressure.
The utility model is made up of connecting tube, air pump etc., during use, gas is entered debugging apparatus by throttling valve, each pressure switch is entered again by each branch line, after each components interior fills gas, individual event reverse checkvalve closes external air source automatically, then debugging apparatus connecting tube and pump are turned off, cut off the electricity supply.When debugging its each part member, be connected on the starting-up later time contact of each element with multimeter connecting line, its debugging element internal is vented slowly, its air scavenge contact snap action is made to be working value, be homing action value when supplementing gas contact with money in this action, the difference of their action reset, it is exactly the action master data standard-required of electric elements, each adjustment method is identical with the former, the parts debugging adopting single-phase vent valve to carry out each classification is repaired, treat that the debugging of each parts is complete, if when also needing to check the carrying out of having proofreaded in debugging, also need carry out round trip test from new inflation and exhaust to it, to the parts of the various models of its stand the test, after query, time should be carried out, parameter, press corrector's list, seal and element are put on record preservation, in order to carrying out interim convenient replacing and use to it at the scene.Adopt debugging apparatus of the present utility model that pressure switch is departed from power-supply unit to debug, the debugging efforts of pressure switch can be completed fast, do not affect normal power supply, when site pressure switch goes wrong, change at any time, work efficiency is high, because not being directly debug on power-supply unit, debugging efforts is not by the impact of working time, security, and debugging accuracy is high.
