Abstract
The utility model discloses a grounding dolly for indoor metal armouring draw-out type switch equipment; and the grounding dolly comprises a chasis truck, a mounting base arranged on the chasis truck, a handcart mounting plate arranged on the mounting base, a contact arm connected with the handcart mounting plate, and a contact head arranged on an end portion of the contact arm. Generation of electric shock accidents of maintenance personnel in a maintenance process of 10KV indoor metal armouring draw-out type switch equipment are prevented; and the maintenance personnel are ensured to repair the 10KV indoor metal armouring draw-out type switch equipment under a safe and reliable environment.
Description
Technical field
The utility model relates to a kind of indoor metal armoring draw out switchgear ground connection dolly.
Background technology
The extensive use of 10kV indoor metal armoring draw out switchgear, because its enclosed construction form, in the overhaul of the equipments process, for guaranteeing safety operation, require the major loop, secondary subsidiary loop in the examination and repair system can not charged and reliable ground, otherwise can bring fatal danger to the maintainer.
The utility model content
Main purpose of the present utility model is to provide a kind of safe and reliable indoor metal armoring draw out switchgear ground connection dolly.
For addressing the above problem, the utility model adopts following technical scheme: a kind of indoor metal armoring draw out switchgear ground connection dolly, comprise the chassis car, and be arranged on mount pad on the car of chassis, and be arranged on handcart mounting panel on the mount pad, the contact arm that links to each other with the handcart mounting panel, and be arranged on the contact of contact arm end.
Further, the centre position of described contact arm is provided with insulating cover.
Further, also be connected with the ground connection copper bar below the described contact arm.
The beneficial effect of the utility model indoor metal armoring draw out switchgear ground connection dolly is: prevent that 10kV indoor metal armoring draw out switchgear maintainer in maintenance process from producing electric shock accidents, guarantee that the maintainer overhauls the 10kV indoor metal armoring draw out switchgear under safe and reliable environment.
Description of drawings
Fig. 1 is the schematic diagram of the utility model indoor metal armoring draw out switchgear ground connection dolly.
Embodiment
See also shown in Figure 1, a kind of indoor metal armoring draw out switchgear ground connection dolly of the present utility model, comprise chassis car 1, and be arranged on mount pad 2 on the chassis car 1, and be arranged on handcart mounting panel 3 on the mount pad 2, the contact arm 4 that links to each other with handcart mounting panel 3, and be arranged on the contact 5 of contact arm 4 ends.
The centre position of described contact arm 4 is provided with insulating cover 6.Described contact arm 4 belows also are connected with ground connection copper bar 7.
The chassis structure that this ground connection dolly adopts is consistent with the circuit breaker dolly chassis structure of actual motion; The contact arm 4 of ground connection dolly adopts the contact arm of circuit breaker same model.The circuit breaker dolly basically identical of the structure of ground connection dolly, size and installation site and actual motion, the contact arm 4 of dolly is received bus one side of 10kV indoor metal armoring draw out switchgear, grounded circuit through dolly is connected bus and ground connection copper bar 7, guarantees the bus reliable ground.
Can replace the circuit breaker dolly of actual motion to observe unlatching and closed condition and the one-time contact 5 insertion contact conditions of valve owing to check dolly.Whether normally open by observation and inspection dolly metal dampers baffle plate in being pushed into the process of service position and to put in place, thereby whether the contact arm 4 of judging the circuit breaker dolly is in operation valve is produced discharge or contact and causes short circuit accident.Whether normally insert contact by observation and inspection dolly one-time contact 5 in being pushed into the process of service position, thereby whether the one-time contact 5 of judging the circuit breaker dolly normally inserts contact, prevents that one-time contact 5 is because of seriously heating accident of loose contact generation equipment.
The beneficial effect of the utility model indoor metal armoring draw out switchgear ground connection dolly is: prevent that 10kV indoor metal armoring draw out switchgear maintainer in maintenance process from producing electric shock accidents, guarantee that the maintainer overhauls the 10kV indoor metal armoring draw out switchgear under safe and reliable environment.
The above only is embodiment of the present utility model, but protection range of the present utility model is not limited thereto, and any variation or replacement of expecting without creative work all should be encompassed within the protection range of the present utility model.Therefore, protection range of the present utility model should be as the criterion with the protection range that claims were limited.
