Description
Technical field
The present invention relates to the switch cubicle in field of electrical equipment.
Background technology
With the fast development of national grid, in power system, the safety of the person and equipment is most important,《Country
18 great anti-accident measures of power network of grid company》In, its Section 1 and Section 12 are pointed out respectively：Prevent personal injury thing
Therefore and prevent GIS, switchgear accident.Existing switch cubicle includes front and back in the cabinet with breaker chamber, breaker chamber
It is assemblied in guiding movement in the earth handcart in cabinet, breaker chamber and auxiliary switch is provided with front side of earth handcart, it is auxiliary
Help and switch the switch lever that the axis for including housing and being arranged at by back-moving spring on housing extends along the longitudinal direction.In order to prevent
Human casualty accident and switchgear accident, in the operation maintenance maintenance in switch cubicle later stage, using earth handcart in switch cubicle
Breaker chamber operation when being moved to operating position forward, it is necessary to provide ground connection letter to secondary system control end by auxiliary switch
Number, its specific means be earth handcart strike switch lever make after switch lever move so that change auxiliary switch contact opening and closing shape
State.Existing this switch cubicle has problems in that：Reduce in accordance with miniaturization and as far as possible and take the principle for using space, open circuit
The volume of device room originally should not be very big, but be able to allow earth handcart to be moved to operating position Shi Rengyou spaces and can install
Auxiliary switch, must just increase the size on breaker chamber fore-and-aft direction, and this adds increased breaker chamber and whole switch cubicle
Space-consuming.
The content of the invention
It can reduce the switch cubicle of size on breaker chamber fore-and-aft direction it is an object of the invention to provide a kind of.
In order to solve the above problems, the technical scheme is that：
It is oriented to along the longitudinal direction in a kind of switch cubicle, including auxiliary switch and the cabinet with breaker chamber, breaker chamber
Movement is equipped with earth handcart, and the auxiliary switch is arranged on the outside of the cabinet, the cabinet or opened by switch base
Close and be hinged with interlock plate on seat, the hinge axes bearing of trend and fore-and-aft direction of interlock plate are perpendicular, and one end of interlock plate is through cabinet
The resigning hole set on body is extend into breaker chamber for coordinating with the earth handcart pushing tow, and the other end of interlock plate is stretched
Go out to the outside of cabinet to be connected with the switch lever of the auxiliary switch.
The interlock plate is connected by being hinged and connected with switch lever with switch lever.
The earth handcart and auxiliary switch are located at the same side of the interlock plate.
The earth handcart includes trolley body and is arranged at the yoke frame of trolley body front end, and the yoke frame includes
The U-board of recess backwards and the connecting plate for being arranged at the U-board left and right sides, the connecting plate are fixedly arranged in the trolley body.
The connecting plate is secured by bolts in the trolley body.
Beneficial effects of the present invention are：When needing to carry out Maintenance and Repair to switch cubicle, earth handcart is moved towards interlock plate
It is dynamic, when earth handcart is moved to operating position, the part that earth handcart pushing tow interlock plate is extend into breaker chamber, interlock plate
The other end drive auxiliary switch switch lever movement, so as to change the contact open and-shut mode of auxiliary switch, to realize that auxiliary is opened
Close to miscellaneous equipment and ground signalling is provided.Auxiliary switch is set to the outside for arriving cabinet by the setting of interlock plate, interlock plate is not
The space on the fore-and-aft direction of breaker chamber is taken again, so as to reduce the size on breaker fore-and-aft direction, is conducive to breaking
The miniaturization of road device room and whole switch cubicle makes.

Embodiment
A kind of implementation of switch cubicle is for example shown in Fig. 1 ~ 7：Cabinet 4 including auxiliary switch 7 and with breaker chamber, auxiliary
The switch lever 11 that the axis that switching includes housing and be arranged at by back-moving spring on housing extends along the longitudinal direction, auxiliary switch
Belong to prior art, its concrete structure is no longer described in detail.Guiding movement is equipped with earth handcart 1 along the longitudinal direction in breaker chamber,
Earth handcart includes trolley body 2 and is arranged at the yoke frame 3 of trolley body front end, and yoke frame includes U-board recess backwards
And the connecting plate of the U-board left and right sides is arranged at, connecting plate is secured by bolts in trolley body.Auxiliary switch passes through switch
Base is arranged at the outside of cabinet, in the present embodiment, and switch pedestal is fixedly arranged on the bottom of cabinet 4 by bolt, i.e., auxiliary is opened
Close 7 downsides for being arranged at cabinet, switch pedestal is included in spaced two L shaped plates 15,6 in left and right, two L shaped plates by the
One jointed shaft 9 is hinged with interlock plate 5, and the hinge axes of interlock plate 5 are vertical with fore-and-aft direction, is provided with cabinet and interlock plate phase
Corresponding resigning hole, the upper end of interlock plate is extend into breaker chamber for coordinating with the pushing tow of yoke frame 3 through resigning hole, interlocking
The lower end of plate is extend out to the downside of cabinet and is hinged and connected with the switch lever 11 by the second jointed shaft 8 and auxiliary switch, and auxiliary is opened
Close the rear side that interlock plate is respectively positioned on earth handcart.Figure middle term 14 represents to prevent the opening that the second jointed shaft is deviate from interlock plate
Pin.
The setting of yoke frame causes earth handcart to be mutually distinguishable with circuit breaker cart, i.e., without yoke frame on circuit breaker cart,
Interlock plate must not be touched, earth handcart is in breaker chamber by testing position（Shown in Fig. 2）Along left rail 13, right rail 12
It is moved to operating position forward（Shown in Fig. 3）, the interlock plate that the yoke frame pushing tow of trolley body front end is extend into breaker chamber
Part, under the thrusting action of yoke frame, interlock plate is rotated centered on bearing pin, so as to drive the switch lever of auxiliary switch backwards
Motion is to change contacts status, and when earth handcart returns to testing position by operating position, switch lever is in action of reset spring
It is lower to reset.When interlock plate drive switch lever is moved backwards, because interlock plate is tumbler, so switch lever is not the flat of standard
It is dynamic, but auxiliary switch allows interlock plate to have such kinematic error.
In other embodiments of the invention：Interlock plate can also be connected by linkage and switch lever, so
Switch lever can obtain more preferable translation action, and simply linkage can increase the structural complexity of whole switch cubicle；Auxiliary is opened
Pass and grounding trolley can also be located at the both sides of interlock plate respectively；Yoke frame directly can also be fixedly welded in trolley body,
Yoke frame can not also be set, and now pass through the direct pushing tow interlock plate of trolley body；Auxiliary switch also with the left side that is placed in cabinet or
Right side, now the hinge axes of interlock plate are vertically extending.
