Description
Technical field
The utility model relates to electric test device technique field, especially a kind of electroscope trigger voltage test unit.
Background technology
When the test of electroscope trigger voltage just refers to the electrode of galvanoscopic contact 15%～40% rated voltage, its hummer, the whether normal sounding and luminous of illuminator.According to < < managing security tools and instruments testing regulations > > requirement, electroscope carries out a periodic inspection every year.
But there is no so far special-purpose test unit, but complete test with a control box and a testing transformer.During test, a testing crew boosts with control box, and high pressure is exported by testing transformer high-pressure stage, and the hand-held electroscope of another people, by galvanoscopic contact testing transformer high-pressure stage.Operating personnel must be zero slowly to boost continuously successively from voltage, until hummer, illuminator sounding and luminous, then whether voltage is more now within 15%～40% rated voltage interval, to determine that whether it is qualified.If at voltage hummer, illuminator sounding and luminous during lower than 15% rated voltage, trigger voltage is too low, if at voltage hummer, illuminator sounding and luminous during higher than 40% rated voltage, trigger voltage is too high.Both of these case surface electroscope trigger voltage is all defective.
Existing test apparatus once boosts and can only complete the test of electroscope trigger voltage, complete same electric pressure electroscope trigger voltage test in enormous quantities, will repeatedly boost, step-down.Like this, cost test period is long, inefficiency, poor stability.

Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model test unit.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail, the description of this part is only exemplary and explanatory, should not have any restriction to protection domain of the present utility model.
A kind of electroscope trigger voltage test unit as shown in Figure 1, the dividing potential drop electric capacity 9 being equated by electric capacity, 10, 11, 12, 13, 14, 15, the earthy annealed copper wire 29 of 16 use is equidistantly composed in series circuit, be fixed in insulating bar 26, on insulating bar 26, get out aperture, from each dividing potential drop electric capacity two ends, by conducting rod, draw high pressure, conducting rod one end is welded on annealed copper wire, the other end is threaded, with all press Metal Ball 1, 2, 3, 4, 5, 6, 7, 8 join, on each conducting rod, cover has insulating cylinder 17, 18, 19, 20, 21, 22, 23, 24, isolate with insulating bar, preventing that insulating bar is dirty causes over the ground electric discharge, connecting and disconnecting of the circuit can be by showing on earth terminal circuit that pilot lamp 25 shows, insulating bar 26 is fixed on base 28, ground wire 30 is connected on ground connection set bolt 29, by earthing pole 31 ground connection.
The utility model product is according to series circuit voltage divider principle, when in a circuit, and several different impedances of connecting, the voltage that get each impedance both sides is directly proportional to the ratio of this resistance value and total resistance.We obtain according to testing transformer maximum permissible current Im and galvanoscopic highest voltage level Um the resulting impedance Zm being series in circuit, then this resulting impedance is replaced with the little impedance Z n of several same impedance value, make these little impedance sums equal resulting impedance.According to physical size size and the electrical specification of thermal value size and impedance, we have chosen pure electric capacity is that element forms series circuit.Consider high-tension arcing distance over the ground, capacity cell is assembled into column form, be encapsulated in insulating bar, voltage is drawn from insulating bar hole by electrode.
In the utility model, all press bead 1 to connect the high-pressure stage of testing transformer, by control box, control, be raised to assigned voltage, on 2,3,4,5,6,7,8 electrode beads, obtain respectively 40% Ue, 35%Ue, 30%Ue, 25%Ue, 20%Ue, 15%Ue, 10%Ue(Ue is electroscope respective level rated voltage).Electroscope to be detected since 8 to 2 is clicked successively, sounding and luminous on which electrode bead now, trigger voltage is exactly the voltage that this bead is corresponding.Test one, next can test successively next electroscope, need not remove again voltage raising and reducing.Be completed, powered-down after step-down, with discharging rod electric discharge, test finishes.
Testing crew as long as test on these voltages successively, just can know that whether galvanoscopic trigger voltage qualified, and the electroscope that completes same electric pressure in enormous quantities is tested, need not be again voltage raising and reducing repeatedly.The utility model can be realized the electroscope test of different electric pressures, with once boosting, can occur all voltages between 10%～40% rated voltage.Like this, the test duration greatly reduces, and efficiency significantly improves, and the safety of testing crew is ensured.
The 10kV electroscope trigger voltage of take test is example, and in conventionally test process, testing tool is a control box, a 50kV testing transformer.If tester has two people, one people holds electroscope and rides over step-up side, another people's operating operation case boosts, monitor voltage table, voltage is sent by testing transformer high-pressure side simultaneously, in the process being risen by 0～15% rated voltage at voltage, the personnel of boosting must concentrate one's energy, dig-in voltage table, by testing transformer no-load voltage ratio, converse institute's up voltage, with 15%～40% rated voltage contrast.
Take 10kV, 35 kV, 110kV electric pressure electroscope is example, and quantity is respectively 100, and total quantity is 300., before this invention, need to not boost 300 times, step-down 300 times.
And testing tool of the present utility model is a control box, a 50kV testing transformer, the film of voltage table and development is weighed device.If tester has two people, one man operation control box directly boosts to 40% rated voltage, voltage is sent by testing transformer high-pressure side, and another people holds electroscope and at voltage, weighs device electrode and draw on pile crown and take successively from the bottom to top examination, whether verifies sounding or luminous.
Use after this utility model, 10 kV electric pressure electroscopes only need boost 1 time, and step-down 1 time can complete 100 electroscope trigger voltage tests.35 kV, 110kV electric pressure electroscope only need boost 1 time respectively, step-down 1 time.So altogether boost 3 times, step-down 3 times.As can be seen here, boost, step-down number of times greatly reduces, test efficiency obviously improves.
