Middle string is equipped with isolation cabinet handcart test contact, mother cabinet handcart test contact and back door electromagnetic lock, and it is high to be equipped with isolation cabinet side for also string
Press electrification display.
The beneficial effects of the utility model are: female by being concatenated in each handcart locked loop of mother cabinet and isolation cabinet
Join cabinet back door travel switch and isolation cabinet back door travel switch, when maintenance, when mother cabinet breaker closes a floodgate or any back door stroke
Switch is opened, and mother cabinet handcart and isolation cabinet handcart can not shake all in blocking to operating position；When maintenance finishes,
After mother cabinet back door travel switch and isolation cabinet back door travel switch are all closed and in the state of busbar breaker disconnection, isolation
Operation can be implemented in cabinet and the locking unlock of mother cabinet handcart, operator；When high pressure is not charged, and cabinet handcart and mother cabinet is isolated
In the case of handcart returns to testing position, mother cabinet back door and isolation cabinet back door could all be unlocked, and repair and maintenance personnel can just pacify
Full disengaging.
The utility model can strict guarantee isolation cabinet handcart be unable to on-load operation, in turn ensure only after mother cabinet
Under conditions of door and isolation cabinet back door are all closed, mother cabinet handcart can just be pushed into combined floodgate.Mother cabinet and isolation the two-way of cabinet close
Lock effectively prevents the serious three-phase shortcircuit accident due to caused by the electric arc of disconnecting link generation when runner wagon on-load push-in, has
Effect prevents the generation of safety accident, it is ensured that the safe operation of electric system.
Detailed description of the invention
Fig. 1 the utility model mother cabinet secondary control schematic illustration；
Cabinet secondary control schematic illustration is isolated in Fig. 2 the utility model.
Specific embodiment
The utility model is described in more detail with reference to the accompanying drawing.
The technical solution of the utility model is: concatenating mother cabinet in each handcart locked loop of mother cabinet and isolation cabinet
Back door travel switch and isolation cabinet back door travel switch, when being overhauled, mother cabinet breaker closes a floodgate or any back door stroke
Switch is opened, and mother cabinet handcart and isolation cabinet handcart can not shake all in blocking to operating position；When mother cabinet and isolation
Cabinet all overhauls when finishing, if any back door travel switch is not turned off, mother cabinet handcart and isolation cabinet handcart are still all located at this time
In blocking, only mother cabinet back door travel switch is opened or isolation cabinet back door travel switch is opened or busbar breaker is closed a floodgate
When, blocking the case where could unlocking, effectively back door being avoided to be not turned off of mother cabinet handcart and isolation cabinet handcart
Under, personnel influence Personal Risk and network system safety after entering by mistake through.
It is provided with mother cabinet handcart in mother cabinet, corresponding handcart locked loop is additionally provided in mother cabinet；It is isolated in cabinet
It is provided with isolation cabinet handcart, is isolated in cabinet and is additionally provided with corresponding handcart locked loop, go here and there and set in each handcart locked loop
There are mother cabinet back door travel switch XK1 and isolation cabinet back door travel switch XK2.
Mother cabinet is additionally provided with mother cabinet back door locked loop, and it is high to be equipped with mother cabinet side for string in the locked loop of mother cabinet back door
Electrification display HL1, mother cabinet handcart test contact S1, isolation cabinet handcart is pressed to test contact S2 and back door electromagnetic lock DSN1.Every
It is additionally provided with isolation cabinet back door locked loop from cabinet, string in the locked loop of cabinet back door is isolated and is equipped with isolation cabinet side HV live displaying
Device HL2, mother cabinet handcart test contact S1, isolation cabinet handcart test contact S2 and back door electromagnetic lock DSN2.
Mother cabinet and isolation cabinet in operation and maintenance, guarantee only have busbar breaker separating brake after, mother cabinet back door and every
Under conditions of all closing from cabinet back door, the handcart locked loop of runner wagon just be can turn on.And if only if in the not charged situation of high pressure, after
Door unlock, repair and maintenance personnel can just pass in and out safely.
Fig. 1 is the utility model mother cabinet secondary control schematic illustration.The lock-in control of mother cabinet are as follows: isolation cabinet back door
Travel switch XK2 and mother cabinet back door travel switch XK1 contact seal in the handcart locked loop of mother cabinet simultaneously, and limitation only exists
I.e. mother cabinet back door travel switch XK1 and isolation cabinet back door stroke are opened after the back door of mother cabinet and the back door of isolation cabinet simultaneously close off
It closes XK2 contact to be all closed, the circuit handcart latching electromagnet Y1 of mother cabinet just can turn on, and mother cabinet breaker QF can just push over work
Make position combined floodgate.When mother cabinet is in testing position S1, and isolation cabinet is also at testing position S2, and in the not charged situation of high pressure
Lower HL1 junction closure, mother cabinet back door electromagnetic lock DSN1 electrification are attracted unlock, and mother cabinet back door can be just safely opened.
Fig. 2 is that cabinet secondary control schematic illustration is isolated in the utility model.The lock-in control of cabinet is isolated are as follows: when mother cabinet is disconnected
Road device QF is in gate-dividing state, i.e. mother cabinet back door travel switch XK1 and isolation after mother cabinet and isolation cabinet back door simultaneously close off
Cabinet back door travel switch XK2 contact is all closed, auxiliary contact QF closure, and the handcart locking circuit Y2 that cabinet is isolated just can turn on.Electricity
Magnet Y2 could charge actuation, and handcart can just promote release.When mother cabinet is in testing position S1, isolation cabinet is also at test
When the S2 of position, and the HL2 junction closure in the not charged situation of high pressure, isolation cabinet back door electromagnetic lock DSN2 electrification are attracted unlock, every
It can be just safely opened from cabinet back door.
Both strict guarantee isolation cabinet handcart is unable to on-load operation to this project and measures, in turn ensures only after mother cabinet
Under conditions of door and isolation cabinet back door are all closed, mother cabinet handcart can just be pushed into combined floodgate.That is, isolation cabinet back door only has
When mother cabinet is in testing position S1, and isolation cabinet is also at testing position S2, and the not charged (contact of HL1 and HL2 of high pressure
For closure) in the case where, the back door that cabinet is isolated could open.When mother cabinet breaker close a floodgate or mother cabinet back door travel switch or
Cabinet back door travel switch is isolated to open, the electromagnet circuit of mother cabinet handcart and the electromagnet circuit of isolation cabinet handcart will power off
Locking, akinesia.This two-way locking effectively prevent on-load to cause when being pushed into runner wagon due to the electric arc of disconnecting link generation
Serious three-phase shortcircuit accident, the stringent personal safety that ensure that operator, operation maintenance personnel and service personnel, with
And the safety of network system.
Be presented above the utility model relates to specific embodiment, but the utility model is not limited to described reality
The addition of conventional device in mode, such as circuit, such as resistance are applied, the technical solution formed in this way is carried out to above-described embodiment
What fine tuning was formed, this technical solution is still fallen in the protection scope of the utility model.
