At present, electric power plays vital role in national economy, commercial production, people's daily life, and as the important electrical in power system, high-tension switch cabinet is because of characteristics such as its floor space are little, easy and simple to handle, easy to maintenance, reliable, it is widely used in power plant, transformer station and power distribution network, is especially widely applied in the converting equipment of 10-20kV electric pressure.Thus it is guaranteed that transformer station's inner high voltage switch cubicle safe and reliable operation, become the mission critical of daily power transformation maintenance work.
In recent years, although the running environment of 10-20kV switch cubicle and service behaviour are obtained for bigger improvement, but in actual motion, still expose many problems, be mainly manifested in the following aspects: 1. dangerous spot isolation is not in place；At present, the handcart room great majority of 10-20kV high-tension switch cabinet are middle, when certain interval changes inspecting state into, after pull-out switch cart, portable isolation baffle plate in middle-placed switch cabinet is likely to be due to track bite to be caused failing to completely enclose or bad sealing so that three-phase static contact is still exposed in air.Furthermore owing to movable type isolation baffle plate is not provided with anti-misoperation locking device, operating personnel may touch and open portable baffle plate thus touch charged static contact, the serious threat person, equipment safety by mistake.2. operation maintenance inconvenience.In actual field, the busbar owing to being connected with switch cubicle static contact is still in charging operation state, and isolation baffle plate isolation is the most thorough.Operation maintenance personnel enter handcart room carry out cleaning in cabinet the regular maintenance sex works such as dust time, needs carry out corresponding Preventive Control of Dangerous Spot and safety measure, keep safe distance, add the fussy degree of work difficulty and workflow, make troubles to daily maintenance work；3. affect electrical network power supply reliability.If desired checking experiment work in certain interval switch cubicle, owing to isolation is not thorough, under conditions of being unsatisfactory for safe distance, then needs to disable whole piece bus, expands power failure range, affect electrical network power supply reliability and economy.
At present, the problems referred to above practicable solution of still neither one that market exposes for switch cubicle.Simultaneously take account of switch gear room's free space narrow and small, in order to not affect the working space of staff, therefore, a kind of 10-20kV switch cubicle foldable separating device of invention is Operation of Electric Systems department in the urgent need to, this can not only be substantially reduced operating personnel because touching or isolating the accident probability thoroughly not caused by mistake, and floor space can be reduced, reduce operation maintenance difficulty, reduce power failure range, there is huge economic benefit and safety benefit.
Summary of the invention
It is an object of the invention to the deficiency overcoming prior art to exist, and a kind of simple in construction is provided, foldable, account for area little, easy to use, reliable, good looking appearance, 10-20kV switch cubicle isolating device 10-20kV high-tension switch cabinet in electric substation being effectively isolated.
It is an object of the invention to complete by following technical solution, a kind of 10-20kV switch cubicle isolating device, it includes connecting base and insulation barrier, described connection base be by two L-type underframe bars by between two connecting rods of lateral connection connect and form, the vertical rack bar inside facing edges of described L-type underframe bar is provided with the baffle plate draw-in groove for the vertical grafting of insulation barrier；Bottom the end vertical bar of described L-type underframe bar, two pulleys are at least installed.
As preferably: described connecting rod is connected by center hinge by two, left and right circular metal bar and forms, and one end of one of them bonding jumper is fixed on the end vertical bar of L-type underframe bar, and the other end is provided with screw thread, and is attached thereto by screw；Another bonding jumper one end is fixed on the end vertical bar of another L-type underframe bar, and the other end is coupled together by bearing pin and screw and constituted a folding connecting rod；" halting, Keep Clear-High Voltage " caveat of red sign it is provided with in the middle of described insulation barrier.
As preferably: tubular base vertical bar that described L-type underframe bar is square by cross section and the tubular vertical frame bar that the cross section that one end is vertically connected also is square are made into integration, and block with Plastic cap respectively in the upper end at the two ends of tubulose vertical bar and tubular vertical frame bar；The relative inner face of described tubular vertical frame bar is provided with indent can insert the square groove of insulation barrier from the top down.
Connection base of the present invention can enter the upper track of inspection trolley by pulley, enables the device to be positioned on inspection trolley, provides cost savings；Described folding rod can change the distance between two underframe bars by rotary screw, to adapt to different electric pressure switch cubicle Quarantine Tasks；The underframe bar of described device can rotate by the bearing pin on folding rod, folds up, reduces floor space；Described device uses bulk insulation barrier, can be by completely isolated for the static contact of switch cubicle, it is ensured that the person, equipment safety.
The present invention has simple in construction, foldable, and floor space is little, easy to use, reliable, good looking appearance, can carry out the feature such as being effectively isolated to 10-20kV high-tension switch cabinet in electric substation.
