Description
Technical field
It the utility model is related to a kind of inlet wire and bus connection switch cabinet blocking device.
Background technology
Transformer station's power distribution room of the prior art typically carries out power transmission and distribution management using double circuit power supply mode to electricity consumption,
At present, there are many transformer stations, power program is mostly using double circuit power supply mode in power distribution room, and double loop
Power supply mode does not allow loop-net operation, and transformer station typically, and power distribution room uses intermediate switchgear cabinet, this scheme requirement two mostly
Primary cut-out in the total cabinet of platform inlet wire and mother segmentation cabinet can not close a floodgate simultaneously, can only close two breakers therein；Inlet wire
Total cabinet does mechanical interlocking very positioned at the end positions arranged, mother segmentation cabinet between the centre position of arrangement, three cabinet
Difficulty, the protected mode of electric interlock can only be used, and electric interlock reliability is poor, easy maloperation causes three switch cubicles same
When work, so as to cause severe compromise.
The content of the invention
Technical problem to be solved in the utility model is to provide a kind of inlet wire and bus connection switch that can reliably carry out locking
Cabinet blocking device.
Inlet wire and bus connection switch cabinet blocking device of the present utility model, in the inlet wire that two have middle truck breaker
Procedure lock is provided with by installing plate on cabinet and a mother cabinet cart frame, the dead bolt corresponding positions on side cabinet with procedure lock
Install and be equipped with lockhole, procedure lock dead bolt can extend into locking handcart in lockhole；It is characterized in that：Every incoming line cabinet, mother cabinet
Identical procedure lock is installed on cart frame, in off-position, procedure lock can insert lockhole by key actuated, make handcart without
Method drives；The identical procedure lock of three cart frames is only equipped with two identical keys；Handcart energy when procedure lock is in open mode
Enough operations, key can not be transferred to；Procedure lock is in handcart locking when closing lock-out state and can not operated, and key could be transferred to；
Lockhole on the side cabinet is arranged at handcart type breaker testing position；
When the blocking device is applied to isolation cabinet, the lockhole on side cabinet is arranged at isolated hand car operating position.
Inlet wire and bus connection switch cabinet blocking device of the present utility model, mechanical latching is installed additional on middle truck breaker
Program of device is locked, and the identical procedure lock of three cart frames is only equipped with two and identical keys, key are opened handcart energy after procedure lock
Operation, key can not be transferred in the on-state, could transfer to key when closing lock-out state, can only operate two simultaneously,
Will not maloperation occur three simultaneously action and cause danger, the total cabinet of two inlet wires and mother segmentation cabinet in primary cut-out only
There are two lock identical keys, there can only be two breakers to shake to operating position every time and close a floodgate energization, and another breaker
It is adapted the locking bar put and is firmly locked in testing position.So as to realize that " three close two " purpose, meet fool proof needs.

Embodiment
As illustrated, a kind of inlet wire and bus connection switch cabinet blocking device, have entering for middle truck breaker at two
Procedure lock 5 is provided with by installing plate 3 on line cabinet 7,9 and a cart frame 6 of mother cabinet 8, on side cabinet 2 with procedure lock 5
The relevant position of dead bolt 1 be provided with lockhole, the dead bolt 1 of procedure lock 5 can extend into locking handcart in lockhole；Procedure lock 5 is equipped with key
Identical procedure lock 5 is installed on the cart frame 6 of spoon 4, every incoming line cabinet 7,9 and mother cabinet 8, the procedure lock 5 in off-position
Insertion lockhole can be driven by key 4, handcart is not driven；By rotating key 4, the dead bolt of corresponding program lock 5 stretches out lock
Outside and stretch into the lockhole on side cabinet 2, key can be extracted；If rotating backward key 4, the dead bolt retraction lock of procedure lock 5
Interior, key 4 can not be extracted, and only to be held on procedure lock 5, and procedure lock, the key lock number of incoming line cabinet 7,9 and mother cabinet 8 are identical,
Can mutually it open；Procedure lock, key lock difference between different group switch cabinets, forbid mutually opening, with prevent maloperation other into
The breaker of group switchgear；The identical procedure lock 5 that incoming line cabinet 7,9 and mother cabinet 8 amount to three cart frames 6 is equipped with two
Identical keys 4；Handcart can operate when procedure lock 5 is in open mode, and key 4 can not be transferred to；Procedure lock 5 is in close and locked
Handcart locking can not operate during state, and key 4 could be transferred to；Lockhole on side cabinet 2 is arranged at handcart type breaker experiment
Position；Primary cut-out in the total cabinet of two inlet wires and mother segmentation cabinet is only equipped with two lock identical keys, every time can only
Two breakers are shaken to operating position and closed a floodgate energization, and another breaker is firmly locked in experiment position by the dead bolt of procedure lock
Put.So as to realize that " three close two " purpose.
, only need to be three after user or switch cubicle manufacturer buy this three middle breakers for having installed blocking device additional back
An aperture is made a call on the interior plate of the corresponding middle-placed switch cabinet of platform；Its position is that middle breaker is shaken testing position, locking
Position corresponding to the locking bar of device；As middle breaker need not punch at operating position, blocking device procedure lock
When dead bolt only puts in the hole of intermediate switchgear cabinet, key could be extracted, now breaker can not be shaken from testing position to work
Position.Only by rotating key, dead bolt is retracted, and now key can not be taken out, and middle breaker can be made to shake work
Position.
Blocking device of the present utility model can also be applied in isolation cabinet locking, when blocking device is applied to isolation cabinet,
Lockhole on side cabinet 2 is arranged at isolated hand car operating position, realizes the mechanical interlocking between breaker and isolated hand car, prevents
Only isolated hand car maloperation；With " three close two " breakers except that the isolated hand car that middle isolates cabinet is in working position
Punched when putting, when carrying out closing operation with guarantee, first isolated hand car is shaken to operating position, then circuit breaker cart shaken again
Operating position, closing operation is finally carried out again, when such as carrying out sub-switching operation：First divide breaker, circuit breaker cart from working position
Put and shake testing position, take out the operation that key carries out middle isolation cabinet.
Inlet wire and bus connection switch cabinet blocking device of the present utility model, mechanical latching is installed additional on middle truck breaker
Program of device is locked, and the identical procedure lock of three cart frames is only equipped with two and identical keys, key are opened handcart energy after procedure lock
Operation, key can not be transferred in the on-state, could transfer to key when closing lock-out state, can only operate two simultaneously,
Will not maloperation occur three simultaneously action and cause danger, the total cabinet of two inlet wires and mother segmentation cabinet in primary cut-out only
There are two lock identical keys, there can only be two breakers to shake to operating position every time and close a floodgate energization, and another breaker
It is adapted the locking bar put and is firmly locked in testing position.So as to realize that " three close two " purpose, meet fool proof needs.
