Abstract
The utility model belongs to the electrical equipment field relates to the arc extinction cabinet, concretely relates to isolation protection device of high voltage isolator switch. Including setting up in the switch of bus -bar room A baffle department, the peripheral cladding of the bar breach of bus -bar room A baffle has the flexible insulation wall to overlap, the flexible insulation cut off the cover and postpone switch to room B in and lose no time to cover and arrange. The flexible insulation that sets up cuts off the cover and forms insulating cladding to the high voltage isolator switch in the department with electricity that the bus -bar room was located, and the electricity of just so locating with electricity the high voltage isolator switch cuts off, guarantees maintenance measurement personnel's personal safety. And operating a switch and the activity of feed motion drive flexible insulation wall cover of high voltage isolator switch is guaranteed in the flexible effect that the flexible insulation wall overlaps, and then do not influence the activity of high voltage isolator switch.
Description
Technical field
The utility model belongs to electrical equipment, relates to arc extinction cabinet, is specifically related to a kind of isolating and protecting device of high voltage isolator disconnecting link.
Background technology
The 3-35kV electric power system of China adopts Neutral Point Through Low Resistance mode and neutral point through extinguisher earthing mode mostly.Easily arc grounding is there is in this network system, this overvoltage can reach the phase voltage of 3.5 times, under the long-term continuous action of high overvoltage, the accumulation of insulation must be caused to damage, cause the weak link of insulation at normal phase, and then form phase fault accident.Existing solution adopts arc-extinguishing harmonic-eliminating and overvoltage protection; arc-extinguishing harmonic-eliminating and overvoltage protection are also directly called arc extinction cabinet; be by neutral non-effective grounding electrical network relatively and alternate overvoltage Limiting within the scope of electric power netting safe running; the various overvoltage of thorough solution, to the harm of equipment and electric power netting safe running, improves the reliability of power supply.
The high voltage isolator disconnecting link of arc extinction cabinet is the connecting rod being connected to bus-bar room across room, its one end connect arc extinction cabinet operating grip, the other end is connected to bus-bar room place.Specifically, operating grip is arranged at arc extinction cabinet Qian Menchu, and bus-bar room offers a bar v notch v in the position near arc extinction cabinet Qianmen, and pull operation handle strip dynamic high-pressure isolating switch disconnecting link does movement in a curve along the opening direction of bar v notch v.Operating grip controls arc extinction cabinet switch, close when pulling handle arc extinction cabinet, one time room is uncharged, but bus-bar room is still charged, because high voltage isolator disconnecting link is also connected with charged bus-bar room, so arc extinction cabinet inner high voltage isolating switch disconnecting link is charged at bus-bar room place, will exist like this arc extinction cabinet need to detect or maintenance time, operating personnel enter a room and carry out keeping in repair the charged place touching this high voltage isolator disconnecting link and cause unexpected personal injury and property loss.
Summary of the invention
The utility model object is to provide a kind of isolating and protecting device of high voltage isolator disconnecting link, cuts off the electricity at the charged place of high voltage isolator disconnecting link, ensures the personal safety of maintenance conditions personnel.
In order to realize above object; the technical solution adopted in the utility model is: a kind of isolating and protecting device of high voltage isolator disconnecting link; comprise the disconnecting link being arranged at bus-bar room A dividing plate place; the periphery of the bar v notch v of bus-bar room A dividing plate is coated with flexible insulation and cuts off cover, and described flexible insulation cuts off cover postpones for tightening to the disconnecting link in a room B and cover layout.
Technique effect of the present utility model is: the flexible insulation of setting cuts off cover and forms insulating wrapped to high voltage isolator disconnecting link at the charged place at bus-bar room place, so just the electricity at the charged place of high voltage isolator disconnecting link is cut off, ensure the personal safety of maintenance conditions personnel.And the flexibility effect that flexible insulation cuts off cover be ensure high voltage isolator disconnecting link operating a switch and feed motion to drive flexible insulation to cut off cover movable, and then the activity of not impact to voltage isolating switch disconnecting link.
Accompanying drawing explanation
Fig. 1 is side-looking structural representation of the present utility model;
Fig. 2 is main TV structure perspective view of the present utility model.
Embodiment
With reference to accompanying drawing; a kind of isolating and protecting device of high voltage isolator disconnecting link; comprise the disconnecting link 10 being arranged at bus-bar room A dividing plate place; the periphery of the bar v notch v of bus-bar room A dividing plate is coated with flexible insulation and cuts off cover 20, and described flexible insulation cuts off cover 20 postpones for tightening to the disconnecting link 10 in a room B and cover layout.
The flexible insulation arranged cuts off cover 20 pairs of high voltage isolator disconnecting links 10 and forms insulating wrapped at the charged place at bus-bar room A place, so just cuts off the electricity at the charged place of high voltage isolator disconnecting link 10, ensures the personal safety of maintenance conditions personnel.And flexible insulation cut off the flexibility effect of cover 20 be ensure high voltage isolator disconnecting link operating a switch and feed motion to drive flexible insulation to cut off cover 10 movable, and then the activity of not impact to voltage isolating switch disconnecting link.
Preferably, described flexible insulation cuts off the tapered shape of cover 20, and with reference to Fig. 2, the cone base fabric of taper is placed on the bar v notch v of bus-bar room A dividing plate, and the vertex of a cone of taper extends to disconnecting link 10 place place.
Further preferred, described flexible insulation cuts off at the bottom of the cone of cover 20 and covers whole bus-bar room A dividing plate, and layout is tightly covered in the stage casing that the vertex of a cone that flexible insulation cuts off cover 20 is postponed to disconnecting link 10.Like this with regard to limits, the electricity partition that ensure that the charged place of high voltage isolator disconnecting link 10 completely.
Flexible insulation cut off cover 20 arrange at the position place being positioned at disconnecting link 10 strengthen flexible insulation cut off cover 20 tightly cover step up cover 30.
With reference to Fig. 1, the cover 30 that steps up of setting ensures that flexible insulation cuts off cover 20 and tightens at disconnecting link 10 and cover layout, ensures that flexible insulation cuts off cover 20 and can not come off.
