Like Fig. 1, the utility model isolating switch proving installation conveniently carries out the testing current of electrical equipment, and counts handled easily automatically.The utility model provides a kind of isolating switch proving installation, realizes the automatic lifting pressure, and the qualified counting of metering tested product improves the simplicity of operation.For solving above-mentioned technical matters; The utility model provides a kind of current testing device of electrical equipment; Comprise power transfer device; Connect regulator, test protective device and the operation protection device of power transfer device respectively, the operation protection device connects regulator and counting assembly respectively, and said regulator, test protective device, operation protection device and counting assembly connect the electrical equipment that needs test with test respectively.
The current testing device of the electrical equipment of the utility model also comprises lighting device that connects power transfer device and the cooling fan that is connected power transfer device.The current testing device of the utility model has increased the safety test protective device of test; Wherein, the safety test protective device comprises that said test protective device comprises acoustic-optic alarm, temperature protective device, instrument display device, time display apparatus and distance alarm device.
In the specific embodiment of the utility model, test as electrical equipment with isolating switch, proving installation can adopt 220V/50HZ or adopt the 220V/400HZ power supply mode through switch, is described in detail below in conjunction with Fig. 2.
The proving installation of the utility model comprises manually, operates automatically two kinds of operator schemes.If when selecting automatic operation mode, switch 2 is pulled to automatic catch bit manipulation pattern, select power supply mode, with switch 1 remove to 220V/50HZ test both opens device be example.Relay K A5 work, KA5-1 connects, and KA5-2 breaks off; Isolating switch to be tested is inserted on U, the W point, and adjustment microswitch position makes it to aim at isolating switch scram position to be tested, presses switch S B1; Power light is bright; By switch S B2 relay K A1 work, KA1-1, KA1-2, KA1-3, KA1-4, KA1-5 connect reometer, counter, thermometer energized.This moment can be by switch S B3 or SB4 start illumination device or refrigerating fan device.The infrared sensor work of worktable left side, if there is the people movable in 0.5 meter, dangerous tip system start-up sound and light alarm is to prevent the accident of human electric shock.Contactor KM3 work, regulating circuit voltage auto zero, regulating circuit motor have two kinds of speed states: (1) constant speed receives potentiometer W1 control (speed can be provided with voluntarily); (2) stepless change is manually controlled by potentiometer W2, with potentiometer W2 modulating speed zero setting point, is set the test duration of the time relay, and the temperature of thermometer in main test circuit contact is set; Draw back at a distance from retaining (at a distance from having kept off people, electric buffer action, having electromechanical linkage) MN1 and connect, solid-state relay SSR1 connects, contactor KM5 work, and KM5-1 connects; Press switch S B9, relay K A3 work, KA3-1, KA3-3, KA3-4 connects; KA3-2 breaks off, contactor KM2 work, and solid-state relay SSR2, SSR3 connect, contactor KM2 work, 2 work of buck motor M; Relay K A4 work, KA4-1 breaks off, contactor KM6 work, KM6-1, KM6-2, KM6-3, KM6-4 connect, and regulating circuit begins to boost automatically; Through current transformer, the test circuit electric current raises, and when reaching the measuring current value, presses switch S B6, controlled by potentiometer W2, and the regulating circuit motor speed is zero; The test circuit electric current is not rising, relay K A2 work, and KA2-1 connects self-locking, and the KA2 normally opened contact is connected; Normally closed contact breaks off, and time relay sj 1 (positive time limit), SJ2 (inverse time lag) work are clocked, and numeration (counter band memory hold function) test job begins.
Numeral shows that reometer shows measuring current numerical value (this table has the characteristic that outage back measuring current peak value keeps), increases because the resistance of circuit raises with temperature, and electric current reduces, and is constant for keeping electric current, and adjustment potentiometer W2 is with the current value that guarantees that test is required.
(1) in regulation test duration and regulation measuring current value scope, will touch microswitch during breaking when isolating switch to be tested, make it disconnection, contactor KM6; Relay K A3 quits work, and KA3-2 connects, contactor KM3 work; Regulating circuit voltage auto zero, system will cut off the test circuit power supply automatically, and numeration is effectively; Qualified products, test job is accomplished.
(2) when isolating switch to be tested is less than regulation measuring current value during with regard to breaking, system also will cut off the test circuit power supply automatically, and reason is the same, but does not clock. do not count.
(3) in regulation test duration and regulation measuring current value scope, do not have breaking when isolating switch to be tested, time relay sj 2 (inverse time lag) quits work when reaching setting value, and time relay normally closed contact SJ2-1 breaks off; Contactor KM6. relay K A3 normally opened contact breaks off, and normally closed contact is closed, and KA3-2 connects; Regulating circuit voltage auto zero, system will cut off the test circuit power supply automatically, reach purpose of saving; Product is defective not to count, and test job is accomplished.
(4) in test process because contact U, W point increase in temperature reaches when temperature is set, warning system starts, alert prevents scald after test job is accomplished, solid-state relay SSR1 quits work therebetween.Because contactor KM5-1 continues to keep on-state, system's operate as normal is accomplished until test job.If pole temperature is higher than when temperature value is set, test macro can not start once more, have only when temperature is lower than desired temperature by the time to start once more.
The test pattern effect of the kinds of protect of the utility model collection time device, temperature device, counting device, risk distance warning device, meter displaying device; To with big current parameters serve as test to the design on the test macro of picture owing to adopt kinds of protect measure and correlation technique; Make the staff safer; Easy to operate, increase work efficiency, reduce cost.
The utility model the above-mentioned embodiment that lifts only with the explanation the utility model principle and structure; But not in order to restriction the utility model; The equivalent transformation of all this kind foundation or prior art is that those skilled in the art obviously learns, ought to be within the category of the disclosed protection of the utility model.
