Description
Technical field
The utility model relates to a kind of ground connection car, refers in particular to a kind of ground connection car that directly applies to mid-switchgear manufacturing industry and power supply unit.
Background technology
At home and abroad in the Xian Jin medium-voltage equipment; domestic KYN28A-12 armouring middle metal enclosed switchgear (or GZS1 switchgear of ABB AB) is applicable to 3.6～12KV three-phase alternating current 50HZ electrical network; as accepting and distribute electric energy, and circuit is carried out the usefulness of control, monitoring and protection.And possesses perfect, reliable anti-misoperation function.VD4, VM1 series and the VDS series vacuum circuit-breaker that can join ABB.The said equipment has a kind of busbar grounding device, i.e. ground connection car.In circuit or overhaul of the equipments, the ground connection car is advanced to realizes busbar grounding in the switch cubicle.
At present, the mid-withdraw-type switchgear of the metal armouring of various production firms production and sales, because the difference that circuit breaker is selected for use, required supporting ground connection bassinet structure manufacturing also has nothing in common with each other, each other can not be general.The user has purchased the different metal armourings mid-withdraw-type switchgear that different manufacturers is produced, and just causing institute matching used ground connection car type class is various again can not be general, brings trouble in management and the keeping to the user simultaneously.
According to user's needs, be grounded general that car can be in each switch cubicle equipment, reduce the specification of ground connection car, user's management is simplified.
The utility model content
The utility model provides a kind of adjustment height ground connection car of mid-switchgear, and is simple in structure, in light weight, realize that sets of contacts is detachable, and the utility model is applicable to the mid-withdraw-type switchgear of different metal armourings.
The utility model solves the problems of the technologies described above by the following technical programs:
A kind of adjustment height ground connection car of mid-switchgear is characterized in that, comprising: sets of contacts; One is used to install the frid structure of sets of contacts; Be provided with the support of the movable part that is connected with the frid structure; The screw mandrel that is used for the movable part of driving arm; What be arranged on the support bottom carries push plate and chassis.
Described sets of contacts comprises contact arm, earth connection and the mounting panel that is used to install contact arm and earth connection.
Described sets of contacts and frid structure are fixed by knob.
The movable part of support is connected by roll sleeve with the frid structure.
Describedly propose push plate and be installed in two long lumbar holes of support bottom by roll sleeve, the position of proposing push plate is by the latch positioning and fixing.
The utility model carries out the ground connection operation applicable to the mid-withdraw-type switchgear of multiple different metal armouring; Between ground connection car lay-up period, sets of contacts can disassemble from the ground connection car, thereby realizes keeping separately.

Embodiment
In order to make technological means of the present utility model, creation characteristic, to reach purpose and effect is easy to understand,, further set forth the utility model below in conjunction with concrete diagram.
As shown in Figure 1 to Figure 3, the adjustment height ground connection car of a kind of mid-switchgear of the present utility model comprises: sets of contacts 1; One is used to install the frid structure 2 of sets of contacts; Be provided with the support 5 of the movable part 10 that is connected with frid structure 2; The screw mandrel 4 that is used for the movable part 10 of driving arm 5; What be arranged on support 5 bottoms carries push plate 6 and chassis 7.
As shown in Figure 4, sets of contacts 1 comprises contact arm 8, earth connection 3 and the mounting panel 9 that is used to install contact arm 8 and earth connection 3.
As shown in Figure 7, there are two knobs the support both sides, are in horizontal locking state at ordinary times, and when inserting knob 12 with screwdriver, and after clockwise rotating 180 degree, knob 12 is in released state.Otherwise after rotating counterclockwise 180 degree, knob 12 is in locking state.When knob 12 was in released state, sets of contacts 1 can be extracted out from the support top, breaks away from support.Perhaps, sets of contacts can be inserted from the support top, inserts back locking knob 12.Sets of contacts 1 is fixing by knob 12 with frid structure 2, and in the time of in the groove of sets of contacts 1 insertion groove plate structure, turning knob 12 is fixed together sets of contacts 1 and frid structure.Therefore, the sets of contacts 1 of ground connection car can realize separating with support, is convenient to the user so valuable sets of contacts is separated keeping.
As shown in Figure 6, the movable part 10 of support 5 is connected by middle roll sleeve with frid structure 2, and roll sleeve slides in the groove of two side plates 11 of support 5.With box spanner up time rotary screw rod 4, the movable part 10 of driving arm 5, drive frid structure 2 again and move up along support 5, otherwise, then move down, thereby can raise or reduce the height of the sets of contacts 1 in the frid structure, regulate the distance of sets of contacts 1 and bottom surface.
As shown in Figure 5, proposing push plate 6 is installed in two long lumbar holes of support 5 bottoms by roll sleeve, the position of proposing push plate 6 is by the latch positioning and fixing, when the pull-up latch, and revolve and turn 90 degrees, this moment, latch was in the position that breaks away from location hole, proposing push plate 6 can move freely forward or backward, after moving to assigned address, rotate latch, latch can position automatically.
The universal chassis of the mid-withdraw-type switchgear of existing metal armouring is adopted on the chassis 7 of ground connection car of the present utility model.
Before using the utility model the bus contact to be carried out the ground connection operation, must adjust according to top mode, and make parameters such as sets of contacts height, the position of proposing push plate meet will the mid-withdraw-type switchgear of metal armouring of ground connection after, just can carry out the ground connection operation.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The protection range that the utility model requires is defined by appending claims and equivalent thereof.
