Description
Technical field
The utility model relates to the withdrawal mechanism field that is used for distribution board, transformer station or switching device that power supply or distribution use, is specially a kind of fixed switch cubicle inquiry formula interlock.
Background technology
Switch cubicle is the equipment that is used for power delivery, distribution and control; Be provided with the circuit breaker that is used for decompression, under-voltage, overload and short-circuit protection in the switch cubicle, circuit breaker is connected with the isolating switch that is used for electrical isolation, because isolating switch can not the on-load operation; Therefore the operating sequence of isolating switch and circuit breaker has strict demand; The necessary anti-error interlocking of enforce, many at present employing interlock dropout designs, this structure is broken off through circuit breaker and is reached the interlocking purpose; Can cause unnecessary line powering to interrupt, what influence was produced and lived normally carries out.
The utility model content
In order to overcome the defective of prior art, a kind of simple in structure, safe and reliable interlock is provided, the utility model discloses a kind of fixed switch cubicle inquiry formula interlock.
The utility model reaches goal of the invention through following technical scheme:
A kind of fixed switch cubicle inquiry formula interlock comprises frame, blocking lever and spring, has on the frame to close a pin-and-hole and divide the position pin-and-hole; Divide the position pin-and-hole to be positioned at the top of closing a pin-and-hole, the bottom of blocking lever is located on the blocking lever through spring housing, it is characterized in that: also comprise block, backing pin, lock version, supporting plate and sensitive switch; Bottom and block that block is located in blocking lever are positioned at the below of closing a pin-and-hole; Close a pin-and-hole, divide the position pin-and-hole all to form matched in clearance with backing pin, the middle part of blocking lever has vertical chute, and an end of supporting plate connects longitudinal sliding block with bearing pin; Longitudinal sliding block is embedded in vertical chute; The other end of supporting plate connects an end of jam plate with bearing pin and is fixed on the frame, and the other end of jam plate floats with sensitive switch and is connected, and the middle part of jam plate has horizontal concrete chute; The top of blocking lever connects transverse slider with bearing pin, and transverse slider is embedded in the horizontal concrete chute.
Described fixed switch cubicle inquiry formula interlock, it is characterized in that: the junction of jam plate and supporting plate is 1/3～1/2 of a locking bar length to the length of the junction of jam plate and blocking lever.
When the utility model used, when circuit breaker was in "on" position, backing pin was inserted in and closed in the pin-and-hole this moment; The block that is located on the blocking lever is stopped by backing pin; Blocking lever can't move upward, i.e. mechanical latching forced blocking can't be got to disjunction locked position of coupler operation isolation knife, satisfies the locking requirement.When circuit breaker is in gate-dividing state; This moment, backing pin was inserted in the pin-and-hole of branch position, and blocking lever can move upward till block is stopped by backing pin, when blocking lever moves upward; Transverse slider promotion jam plate through the blocking lever top rotates up around the bearing pin that connects jam plate and supporting plate; The other end of jam plate moves upward, and promptly mechanical latching can be got to disjunction locked position of coupler operation isolation knife, and the locked position of coupler switch breaks off simultaneously; The electric blocking closing circuit is got to service position closing circuit conducting when mechanical latching and can electricly be closed a floodgate.
The beneficial effect of the utility model is: 1. can force to guarantee operation sequence, the unnecessary power failure that can avoid mistake to divide circuit breaker to cause again improves power supply quality; 2. compact conformation, interlock is inner at breaker body, and is not connected with lock operation mechanism is rigid, helps the modularization production of equipment and makes things convenient for Installation and Debugging.
