The beneficial effects of the utility model:
The utility model drawer loop experiment power supply adopts contactor control loop to choose from the main bus bar of drawer loop outside, the contactor of controlling in drawer loop for external command closes a floodgate and a minute brake test, and choosing of experiment power supply can not affect drawer loop in the normal operation of service position.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
Fig. 1 is the schematic diagram of the utility model drawer loop experiment power supply.
Embodiment
Shown in figure 1, be drawer loop experiment power supply of the present utility model, for contactor combined floodgate and a minute brake test for drawer loop.
General drawer loop has extraction, test, three positions of work, for MNSG cabinet, these three positions are to control by the handle on the large interlocking gear control and testing board of drawer in actual mechanical process, large interlocking gear allows configuration test, service position auxiliary switch, and withdrawn position does not have too large meaning for the control loop of drawer, in the technical program, ignore, the test position of drawer and service position point are just to realize drawer above-mentioned can provide that experiment power supply is needed have been configured.
The technical program represents that with the contactor control loop 100 of drawer obtains the scheme of experiment power supply, this experiment power supply is by obtaining on the major loop between 380/220V power distribution equipment 200 and on-site control 300, the A phase of 380/220V power distribution equipment 200, B phase, C phase, the end of incoming cables of N phase connection and on-site control 300 is electrically connected, in A phase, B phase, in C phase connection, be provided with the wiring position of the plug-in unit 400 of inlet wire side being connected in series successively from 380/220V power distribution equipment 200 to on-site control 300, the normally opened contact of breaker of plastic casing ZKK, contactor C often leaves main contacts, the wiring position of a plug-in unit 500 of outgoing line side,
The contactor control loop 100 of this experiment power supply comprises test branch road 101, work branch 102, and the contactor of simultaneously connecting with test branch road 101, the work branch 102 wiring position of often opening auxiliary contact C, contactor coil C, outgoing line side secondary inserting piece 600; Described test branch road 101 is in series by the second miniature circuit breaker 2DK and drawer test position stroke interrupteur SW, and the A phase line that described the second miniature circuit breaker 2DK often opens main contacts inlet wire side with contactor is connected, and tie point is ~ A; Described work branch 102 is in series by wiring position, the first miniature circuit breaker 1DK and the drawer service position travel switch YW of inlet wire side secondary inserting piece 700, the front end of the wiring position of described inlet wire side secondary inserting piece 700 connects the A phase connection between 380/220V power distribution equipment 200 and plug-in unit of inlet wire side 700 wiring positions, and tie point is ~ A1; It is in parallel with the closing contact KJ of drawer loop that described contactor is often opened auxiliary contact C, and described contactor coil C and tentaculum are often opened the separating brake contact KJ that is in series with drawer loop between auxiliary contact C; The wiring position of described outgoing line side secondary inserting piece 600 is connected with N phase connection.
Its operation principle is: when drawer is during in test position, plug-in unit 400,500 do not communicate and only secondary inserting piece 600,700 to communicate be non-transformer in drawer, now experiment power supply need to be chosen from the main bus bar of drawer outside, choose ~ A, and now SW in on-state, the main bus bar power supply after 2DK miniature circuit breaker that closes is obtained as the experiment power supply of drawer, combined floodgate, the separating brake experiment work of contactor when drawer can be realized test position by this kind of mode.And SW contact disconnects and YW contacting when drawer arrives service position through testing by pusher, at this moment, in loop, a plug-in unit is connected, if main switch ZKK closes a floodgate in loop, contactor inlet wire side is charged, close 1DK miniature circuit breaker obtain ~ A1 of control loop power supply (power supply N side is uncontrolled, in test position and service position, all connect), so once, secondary circuit all normally works.
