Abstract
The invention relates to an uninterrupted power test residual current protective device which comprises a detection device and a terminal strip fixed on the wall of a distribution box, wherein the detection device comprises a residual current operated protective device fixed in a test box, an intermediate relay and a monitoring lamp, wherein the detection device is connected with a tested residual current operated protective device and an alternating current contactor which are arranged in the distribution box, and a casing of the test box is connected with a grounding box through a connecting wire. The device has simple structure, and an alternating current contact coil can not lose power during the trial jump.
Description
Technical field
The present invention relates to a kind of uninterrupted power test residual current protective device.
Background technology
For guaranteeing correct, the sensitive action of RCD, the operations staff must carry out regular, irregular trial jump inspection to operating aftercurrent action protecting equipment.Generally include tested RCD 3, A.C. contactor 2 and zero sequence current mutual inductor 1 in the existing distribution box; Tested RCD 3 is provided with tested RCD power input line 11 and tested RCD output line 10; Tested RCD power input line 11 is connected with 220V pressure-wire 13; Tested RCD output line 10 is connected with auxiliary relay 5, and zero sequence current mutual inductor 1 is connected with tested RCD 3.And conventional test methods is directly by tested RCD 3 testing buttons, or uses the earth resistance analogue ground, carries out trial jump.In the trial jump process, can make A.C. contactor 2 coil losing electricities cause the circuit instant electricity loss, thereby produce following drawback:
1, the frequent power failure of circuit is to high-end electronic product deleterious impact such as LCD TV, air-conditionings, and particularly during instant messaging such as computer, facsimile machine equipment work, dead electricity may be brought immeasurable loss to the user suddenly; Enterprise below comprehensive, like glassware manufacturing, weaving etc., instant electricity loss can make damage of product, causes the business economic loss.
2, the user misunderstands, and thinks circuit originally in continuous power supply, and the staff gets into electric people from room for causing line tripping.
3, after the circuit instant electricity loss, some loads have the delay protection function, can not recover behind the incoming call at once, thereby cause the supply load loss.
Summary of the invention
The purpose of this invention is to provide a kind of uninterrupted power test residual current protective device.
The technical scheme that the present invention adopts is:
Uninterrupted power test residual current protective device; Comprise checkout gear and the terminal board that is fixed in the distribution tank wall; Said checkout gear comprises RCD, auxiliary relay and the monitoring lamp that is fixed in the test box; Said checkout gear is connected with A.C. contactor with the interior tested RCD of distribution box through terminal board, and the shell of said test box is connected with earth electrode through connecting line.
Said RCD is provided with RCD power input line and RCD output line; Said RCD power input line is connected with auxiliary relay; Said auxiliary relay is connected with the monitoring lamp; Said auxiliary relay is connected with tested RCD output line through terminal board; Said RCD output line is connected with A.C. contactor through terminal board, and said RCD power input line is connected with tested RCD power input line through terminal board.
Advantage of the present invention is: device is simple, and in the trial jump process, ac contactor coil can dead electricity.

Embodiment
As shown in Figure 1; Uninterrupted power test residual current protective device of the present invention; Comprise checkout gear and the terminal board 12 that is fixed in the distribution tank wall; This checkout gear comprises RCD 6, auxiliary relay 5 and the monitoring lamp 4 that is fixed in the test box 7, and this checkout gear is connected with A.C. contactor 2 with the interior tested RCD 3 of distribution box through terminal board 12, and the shell of test box 7 is connected with earth electrode 14 through connecting line.RCD 6 is provided with RCD power input line 9 and RCD output line 8; RCD power input line 9 is connected with auxiliary relay 5; Auxiliary relay 5 is connected with monitoring lamp 4; Auxiliary relay 5 is connected with tested RCD output line 10 through terminal board 12; RCD output line 8 is connected with A.C. contactor 2 through terminal board 12, and RCD power input line 10 is connected with tested RCD power input line 11 through terminal board 12.
Further specify in the face of method of operation down.
With earth electrode ground connection; The auxiliary relay connecting line is numbered a, b; With the RCD output line be numbered c, d
is numbered e, f with the RCD incoming line; Insert a, b, c, d, e, f contact on the terminal board by numbering respectively then; Open the testing apparatus switch, withdraw from the brace of terminal board a, b, carry out normal trial jump test.The process of trial jump test has guaranteed correctness, the sensitivity of test RCD action; Circuit instantaneous power failure when also having avoided the test RCD; Satisfy the demand of user's power supply continuity; Thereby realized that uninterrupted power test residual current moves total protector, improved rural area low-voltage circuit power supply reliability.
