The drawer front panel of the utility model is provided with a drawer handle, a control plate and an unblocking hole. The utility model is characterized in that the drawer front panel is also provided with a circuit breaker operating grip used to control a main switch and a mechanical interlocking device operating grip connected with the mechanical interlocking device of the drawer, the mechanical interlocking device operating grip is provided with a connection position, an experiment position, a pumping position and a separating position, and the circuit breaker operating grip is provided with a separating position and a closing position. The utility model has the advantages that the two operating grips is co-operated to control to ensure the safe and reliable operation of the mechanical interlocking device between the propelling device and the switching operation device of the drawer unit.
Description
Technical field
The utility model relates to low pressure draw out switchgear cabinet, particularly a kind of drawer unit of GCK type low pressure draw out switchgear cabinet.
Background technology
GCK (GCK promptly is that motor control center is closed with pull-out type) type switch cubicle is applicable to the usefulness as distribution and motor centralized control such as power plant, power distribution station, is mainly formed by the various functional unit combinations that are drawer-like, is called for short drawer unit.At present, the propulsive mechanism and the interlocking gear of the drawer unit of the GCK type low-tension switch cabinet that each switchgear assembly producer is produced in the industry, majority is easy propulsive mechanism, adopts the switching manipulation handle be installed on the drawer unit door-plate to realize mechanical chain between drawer and the cabinet.There are a lot of defectives in this drawer unit: 1) do not have test position on the drawer, do not reach requirement (national Specification should have above the fold and indications such as connection, test, extraction, isolation); Though the travel switch of test usefulness has been installed additional in the producer that has on drawer side, reliability does not reach requirement.2) drawer unit door-plate and cabinet link together, and drawer is carried out experimental test, and necessary opening door operation not only bothers but also dangerous.3) the no positioner of each position indication often causes the position inaccurate, does not guarantee the electrical safety reliability.4) drawer does not have anti-drop device, mechanically has the hidden danger to the person.5) under the live testing state that opens the door, it is chain not have machinery between propulsive mechanism and the switch operating mechanism, may cause misoperation to make switch can pull out drawer unit under load-carrying situation, causes electric accident.
The utility model content:
Technical problem to be solved in the utility model is: a kind of novel GCK type drawer unit structure is provided, realizes that the propulsive mechanism and the mechanical chain handling safety between the switch operating mechanism of drawer unit is reliable.
The technical solution of the utility model is:
A kind of novel GCK drawer unit structure, comprise drawer panel and drawer-bottom board, drawer side, plug-in unit on the drawer post-erection plate and secondary plug-in unit, described drawer panel is provided with the drawer handle, control and testing board, unlock hole, it is characterized in that: the breaker operator handle and the mechanical chain mechanism operating grip that is connected with mechanical chain mechanism in the drawer that also are provided with the control main switch on the described drawer panel, has link position on the described mechanical chain mechanism operating grip, test position, extract the position out, four the position indications in separation point position have separating brake position OFF on the described breaker operator handle, two position indications of closing position ON.
Described drawer unit by drawer panel, drawer-bottom board, drawer side, the drawer post-erection plate is integrated constitutes.
Technique effect of the present utility model is:
1) solved the defective that above-mentioned simple and easy drawer unit exists: a) drawer is provided with test position, satisfies industry and user's requirement; B) drawer unit door-plate and drawer are integrated, convenient maintenance, debugging; Position such as c) connection, test, extraction, separation and indication obviously and have positioner; D) on the drawer anti-drop device is arranged, prevent that maintenance personal's drawer that overexerts from coming off and cause device damage, prevents to injure by a crashing object personnel; E) even under the live testing state that opens the door, mechanical chain is arranged also between propulsive mechanism and the switch operating mechanism, can not cause misoperation, safe and reliable.
2) improve product quality and performances, guaranteed reliability of products, safeguarded equipment and personal safety.
3) perfect design has been avoided user's complaint, has reduced the after-sale service expense, has reduced the cost of company.
4) promote the technical grade of product, strengthened competitive strength, safeguarded the brand image of enterprise.
5) above-mentioned advantage has improved the economic benefit of product, has produced social benefit.

Embodiment
According to shown in Figure 1, drawer unit is made into integration by drawer panel 1, drawer drawer-bottom board 3, drawer side 4 and drawer backboard 8, and plug-in unit 9, secondary plug-in unit 10 are housed on drawer backboard 8, realizes chain with cabinet.Shown in Fig. 2-4, on the drawer unit panel 1 except having drawer handle 11, control and testing board 12 to conciliate the shrinkage cavities 13, also be provided with two operating grips, be breaker operator handle 5 and mechanical chain mechanism operating grip 6, control main switch 7 and mechanical chain mechanism 2 respectively, realize the mechanical chain and the indication of each position by two operating grips.Show the 51 liang of indicating positions in closing position 52 and separating brake position on the breaker operator handle 5, have link position 61, test position 62 on the mechanical chain mechanism operating grip 6, extract 64 4 the position indications in position 63 and separation point position out.When mechanical chain mechanism operating grip 6 was locked on the link position 61, to main switch 7 unlockings, at this moment breaker operator handle 5 can close a floodgate and sub-switching operation (OFF-ON).After main switch closed a floodgate, mechanical chain mechanism operating grip 6 was pinned by mechanical interlocks 2, and mechanical chain mechanism operating grip 6 can't switch to extracts position 63 out; When breaker operator handle 5 during in 51 positions, separating brake position, mechanical chain mechanism operating grip 6 switches to extracts position 63 out, and the control loop of main switch 7 all disconnects, and drawer can advance or pull out.When mechanical chain mechanism operating grip 6 was locked in test position 62, main switch 7 disconnected, and control loop is connected, and when mechanical chain mechanism operating grip 6 during in separation point position 64, drawer is locked on the position after pulling out 30mm, and first and second insulating contact all disconnects.
Like this, the compounding practice of operator by two operating grips uses, and guarantees the safe and reliable of the extraction of drawer and insertion, also guarantees personal safety.
