Abstract
The utility model discloses a kind of drawer unit control loop with electric operating breaker of plastic casing, it is the L phases of a fuse FU termination two-phase alternating current, fuse FU another termination electric operating breaker of plastic casing QF B4 ends, closing switch SB1, separating brake switchs SB2, separating brake microswitch SQ2 common port, closing switch SB1 other end concatenation combined floodgate microswitch SQ1 is followed by electric operating breaker of plastic casing QF A2 ends, separating brake switchs SB2, separating brake microswitch SQ2 another public termination electric operating breaker of plastic casing QF A4 ends, electric operating breaker of plastic casing QF A1 terminates the N phases of two-phase alternating current, combined floodgate microswitch SQ1, separating brake microswitch SQ2 is separately mounted to drawer unit interlocking mechanism operation combined floodgate, at open position, the characteristics of the utility model has safe and reliable.
Description
Technical field
The utility model belongs to low-tension switch cabinet technical field, more particularly, to a kind of with electric operating breaker of plastic casing
Drawer unit control loop.
Background technology
The built-in breaker of plastic casing of low-tension switch cabinet correlation standard drawout cubicle must have reliable interlocking, i.e.,：In plastic housing
Drawer can not be extracted out under breaker closing situation, and one-time contact can not disconnect, and to extract drawer out must first disconnect breaker of plastic casing.
The interlocking mechanism of GCS drawers complies fully with standard, but the former design of GCS drawers is only limitted to common manually operated common modeling
Case circuit breaker.In actual use, electrically operated breaker of plastic casing is not yet installed in drawer, reliable interlocking is realized.
The content of the invention
The purpose of this utility model is the deficiency for improving prior art and provides one kind and electronic behaviour is installed in GCS drawers
The breaker of plastic casing of work realizes the electrically operated drawer unit control loop of band reliably interlocked.
The purpose of this utility model is achieved in that a kind of drawer unit with electric operating breaker of plastic casing is controlled back
Road, including electric operating breaker of plastic casing QF, closing switch SB1 and separating brake switch SB2, are characterized in a fuse FU termination
The L phases of two-phase alternating current, fuse FU another termination electric operating breaker of plastic casing QF B4 ends, closing switch SB1, separating brake
SB2, separating brake microswitch SQ2 common port are switched, closing switch SB1 other end concatenation combined floodgate microswitch SQ1 is followed by electricity
Dynamic operation breaker of plastic casing QF A2 ends, separating brake switch SB2, separating brake microswitch SQ2 another public termination electric operating modeling
Case circuit breaker QF A4 ends, electric operating breaker of plastic casing QF A1 terminates the N phases of two-phase alternating current, and described combined floodgate fine motion is opened
Close SQ1 to be arranged at drawer unit interlocking mechanism operation closing position, described separating brake microswitch SQ2 is arranged on drawer unit
At interlocking mechanism's operation open position.
Compared with the prior art the utility model has following distinguishing feature and good effect：The utility model is applied to interior
The GCS drawout cubicles that electric operating breaker of plastic casing realizes interlocking are filled, are installed by the combined floodgate of interlocking operation mechanism, separating brake critical part
Microswitch, microswitch is not moved work, closing position, the sub-gate position of microswitch in mechanism closing position and open position time-division
Access circuit-breaker switching on-off loop is put, so as to realize the reliable interlocking between breaker of plastic casing and drawer.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is a kind of structural representation of the present utility model.
Embodiment
A kind of drawer unit control loop with electric operating breaker of plastic casing, reference picture 1 is a fuse FU termination
The L phases of two-phase alternating current, fuse FU another termination electric operating breaker of plastic casing QF B4 ends, closing switch SB1, separating brake
SB2, separating brake microswitch SQ2 common port are switched, closing switch SB1 other end concatenation combined floodgate microswitch SQ1 is followed by electricity
Dynamic operation breaker of plastic casing QF A2 ends, separating brake switch SB2, separating brake microswitch SQ2 another public termination electric operating modeling
Case circuit breaker QF A4 ends, electric operating breaker of plastic casing QF A1 terminates the N phases of two-phase alternating current, and described combined floodgate fine motion is opened
Close SQ1 to be arranged at drawer unit interlocking mechanism operation closing position, described separating brake microswitch SQ2 is arranged on drawer unit
At interlocking mechanism's operation open position.
During using the utility model, when drawer interlocking mechanism is operated to open position, separating brake microswitch SQ2 is triggered, it is micro-
Dynamic switch SQ2 actions, sub-gate circuit normal work, now microswitch SQ1, which is in disjunction position, does not allow combined floodgate；Drawer interlocking
When mechanism is operated to closing position, combined floodgate microswitch SQ1, microswitch SQ1 action is triggered, now allows switch knob SB1
Inlet wire closing operation；If drawer interlocking mechanism has closed a floodgate in closing position, and breaker of plastic casing QF, carry out extracting drawer unit out
During operation, it is necessary to first pass through open position, separating brake microswitch SQ2 is acted, breaker of plastic casing QF separating brakes (one-time contact disconnection),
It can proceed with extraction, it is ensured that drawer can not extract (one-time contact can not disconnect) out under breaker of plastic casing QF combined floodgate situations,
Breaker of plastic casing QF must first be disconnected by extracting drawer out.
