Abstract
An extra-high voltage movable inspection earthing switch device comprises a movable device and a lifting platform arranged on the movable device. A group of vertical isolation switches are arranged on the lifting platform, and an earthing wire is hung on a wiring terminal of the vertical isolation switches. A movable wheel is arranged on the lower portion of the movable device, and a supporting leg which is capable of being folded to be located and has a fixing effect is further arranged below the movable device. An upper end of the earthing wire is led downwards from a wiring terminal plate of the vertical isolation switches, and sufficient length is reserved. The extra-high voltage movable inspection earthing switch device can move freely, can meet earthing requirements of a plurality of interval devices, and can reduce labor intensity and danger of operation staff during working. The extra-high voltage movable inspection earthing switch device has the advantages of being simple in structure, convenient to use, safe, reliable, attractive and neat in overall appearance and capable of meeting practical and craft requirements, and the like.
Description
Technical field
The Grunding switch gear device of using as ground protection when the utility model relates to repair apparatus in a kind of high-voltage alternating electrical network, particularly a kind of ultra high voltage mobile maintenance Grunding switch gear device.
Background technology
At present, electric power system is installed earth connection and is mainly adopted manual type in maintenance process, because earth connection must be sectional area 25mm
2More than and the qualified multiply soft copper insulated wire of short circuit current, often long, overweight, folder is hung complicated operation and is had danger, but also damages power equipment easily.Exchange in the 1000kV ultra-high voltage AC input transformation engineering, the female design height of the pipe in 1000kV circuit high-voltage shunt reactor loop is 18m in the transformer station.During the examination and repair for high-pressure shunt reactor, need on its loop, articulate earth connection, make whole loop reliable ground, guarantee maintainer's personal safety, and female for the high pipe of 18m, its earth connection is just quite long and heavy, articulates very difficulty of earth connection.Exchanging at present conventional artificial that 1000kV transformer station still adopts articulates earth connection or at specified point fixed inspection earthing switch is set and realize.
The shortcoming that such scheme exists is:
1. manual work articulates earth connection the operations staff is had relatively high expectations, and be difficult for realizing, and labour intensity is bigger;
2. manual work articulates the earth connection operation operations staff is had certain risk;
3. fixed inspection earthing switchgear utilance is low, is in outdoor idle state at ordinary times;
4. fixed inspection earthing switch needs each to join one group at interval if need to satisfy each requirement of electric equipment at interval, invests bigger;
5. fixed inspection earthing switch needs the extra transformer station place that takies.
Summary of the invention
The purpose of the utility model is to overcome the shortcoming of above-mentioned existence, and a kind of ultra high voltage mobile maintenance Grunding switch gear device that can use at a plurality of electric equipments is provided.
The utility model solves the technical scheme that its technical problem adopted: it includes a mobile device; One is installed in the hoistable platform on the mobile device; One group of vertical isolation switch is installed on the described hoistable platform, is mounted with earth connection on the binding post of this vertical isolation switch.
Described mobile device bottom is equipped with moves wheel, and the supporting leg of a deployable location and a fixation also is installed below mobile device; The earth connection upper end draws down from the terminal board of vertical isolation switch, and reserves sufficient length.
Described earth connection matches with a ground stud, and five anti-locksets are installed on this ground stud.
The beneficial effect of the utility model is; Can move freely; Ground connection through electric operating is realized electric equipment will articulate earth connection (4) and change mechanical work into by artificial complex job, the danger in the time of can alleviating operations staff's labour intensity and reduce operations staff's operation.And a covering device can be realized the grounding requirement in a plurality of loops; Simple in structure, use flexibly, simultaneously five anti-lockset designs on the ground stud; Make ground stud can prevent that when articulating earth connection mistake is except that earth connection; Can prevent that when not articulating earth connection mistake from articulating earth connection or go to the wrong way at interval, perfect anti mis-closedown function has effectively ensured maintainer's safety; It has simple in structure, and is easy to use, safe and reliable, and overall appearance, clean and tidy can satisfy characteristics such as practical and arts demand.

Embodiment
To combine below accompanying drawing to the utility model make detailed introduction: Fig. 1,2,3, shown in 4, the utility model includes a mobile device 1, and is installed in the hoistable platform 2 on the mobile device 1; One group of vertical isolation switch 3 is installed on the described hoistable platform 2, is mounted with earth connection 4 on the binding post of this vertical isolation switch 3.
Described mobile device 1 bottom is equipped with moves wheel 9, and the supporting leg 5 of a deployable location and a fixation also is installed below mobile device 1.
Described earth connection 4 matches with a ground stud 7, and five anti-locksets 8 are installed on this ground stud.
In Fig. 1, described vertical isolation switch 3 is fixedly mounted on the hoistable platform 2, and 2 of hoistable platforms are fixed on the mobile device 1, and earth connection 4 upper ends draw down from the terminal board of vertical isolation switch 3, and reserves sufficient length.
In Fig. 2, after the mobile maintenance earthed switch moved to assigned address, supporting leg 5 launched the location and plays the support fixation effect; Earth connection 4 lower ends are connected to the ground stud 7 that ground is reserved; Make whole vertical isolation switch 3 major loop reliable grounds, hoistable platform 2 is raised up to setting height, the action of vertical isolation switch 3; Its swing arm clamp is lived in the square tube mother and is gone up the fixed contact of installing 6, makes the electric equipment reliable ground.
Described hoistable platform 2 can be obtained from the power supply that mobile device 1 carries with the required power supply of vertical isolation switch 3 electric operatings.
Five anti-locksets 8 are set on the described ground stud 7, satisfy fool proof requirement in the transformer station.
