Description
Technical field
This utility model relates to a kind of switch cubicle parts, especially a kind of interlocking device of switch cabinet.
Background technology
Switch cubicle needs to meet " five prevent " safe design requirement, i.e. 1) prevent by mistake point, close chopper；2) prevent on-load from dividing, close disconnecting switch；3) band cable address (conjunction) earth lead (earthed switch) is prevented；4) anti-leukorrhagia stopping ground wire power transmission；5) mistakenly entering charged chamber is prevented.For the 5th) band of item electric isolution, it is desirable to must there is isolation between switch cabinet electrified part and people, prevent from injuring personal safety.But existing switch cubicle product, after door hanging can automatic unlocking switching manipulation, owing to cabinet door is protected without door lock, random personnel are the most operable, thus cause the safety issue of personnel.Switch cubicle is after installing, and workmen is under being fitted without the situation of door-plate and door lock, and operation switchs, charged in making cable vault, crisis life safety.
Summary of the invention
For the deficiencies in the prior art, this utility model provides the interlock between a kind of door lock and switch cubicle operation, has advantage easy to operate, that safety is good, effectively prevent the maloperation phenomenon of personnel.
nullThe technical solution of the utility model is: a kind of interlocking device of switch cabinet，Including the door lock being arranged on door of switch cabinet、The locking bar mechanism being fixed in switch cabinet and the rollback interlock plate of the locking bar external part being movably installed in locking bar mechanism，It is characterized in that: described locking bar mechanism includes locking bar frame、Locking bar and back-moving spring，Described locking bar frame is fixed in switch cubicle，Locking bar is installed in rotation on locking bar frame，Back-moving spring two ends are fixing with the bulge loop in the middle part of locking bar and locking bar frame respectively to be connected，The input of locking bar is stretched out outside locking bar frame and is fixed by the dead bolt of connecting plate with door lock，The outfan of locking bar is fixed with power transmission shaft，Described rollback interlock plate includes jam plate main body、Rotor plate and switch baffle plate，It is hinged on rotationally on the installing rack in switch cubicle in the middle part of described jam plate main body，Switch baffle plate and rotor plate are respectively arranged in the both sides up and down of jam plate main body，The end of power transmission shaft is embedded in the bar hole of rotor plate by slide fastener，Switch baffle plate activity is embedded in switching manipulation hole.
Described switch baffle plate, jam plate main body and rotor plate be one-body molded and Z-shaped structure.Described locking bar frame is divided into housing and inside casing, locking bar activity to be embedded in inside casing, and inside casing and housing are all fixedly mounted in switch cubicle.
Work process of the present utility model is: operator use special key to operate door lock, input by dead bolt rotating rod lock, the outfan of locking bar drives the rotor plate bottom rollback interlock plate by power transmission shaft, so that switch baffle plate leaves switching manipulation hole and completes unlocking motion, owing to being provided with back-moving spring on the bulge loop of locking bar and locking bar frame, the homing action of rollback interlock plate then can be realized when cabinet door is shut.
The beneficial effects of the utility model are: interlocking device of switch cabinet provided by the utility model, and operator is only using proprietary key to open cabinet behind the door, could unlock switching manipulation, by preventing the random operation of personnel, ensure its personal safety, and easy to operate, good reliability.
