The handcart room great majority of 20kV high-tension switch cabinet are middle, when certain interval changes inspecting state into, after pull-out switch cart, in
Put the portable isolation baffle plate in cabinet to be likely to be due to track bite and cause failing completely enclosed or bad sealing so that three-phase stationary contact
Head is still exposed in air.Furthermore owing to movable type isolation baffle plate is not provided with anti-misoperation locking device, operating personnel may miss
Touch and open portable baffle plate thus touch charged static contact, the serious threat person, equipment safety.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 is isolated not
Thoroughly.Operation maintenance personnel enter handcart room carry out cleaning in cabinet the regular maintenance sex works such as dust time, need to carry out corresponding danger
Danger point pre-control and safety measure, keep safe distance, add the fussy degree of work difficulty and workflow, to daily O&M
Work is made troubles；3. affect electrical network power supply reliability.If desired checking experiment work in certain interval switch cubicle, due to isolation
Not thorough, under conditions of being unsatisfactory for safe distance, then need to disable whole piece bus, expand power failure range, affect electrical network and power
Reliability and economy.
At present, the problems referred to above practicable solution of still neither one that market exposes for switch cubicle.With
Time in view of switch gear room's free space narrow and small, in order to not affect the working space of staff, therefore, utility model one 10-
20kV switch cubicle foldable separating device is Operation of Electric Systems department in the urgent need to, this can not only be substantially reduced operation people
Member is because touching or isolating the accident probability thoroughly not caused by mistake, and can reduce floor space, reduces operation maintenance difficulty, subtracts
Little power failure range, has huge economic benefit and safety benefit.
Summary of the invention
The purpose of this utility model is the deficiency overcoming prior art to exist, and provides a kind of simple in construction, foldable,
Account for area little, easy to use, reliable, good looking appearance, 10-20kV high-tension switch cabinet in electric substation can be effectively isolated
10-20kV switch cubicle isolating device.
The purpose of this utility model completes 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 pass through between lateral connection two
Root connecting rod connects and forms, and the vertical rack bar inside facing edges of described L-type underframe bar is provided with for the vertical grafting of insulation barrier
Baffle plate draw-in groove；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, wherein
One end of a bonding jumper be fixed on the end vertical bar of L-type underframe bar, the other end is provided with screw thread, and by screw phase therewith
Even；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 with screw by bearing pin
And constitute 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: what tubular base vertical bar that described L-type underframe bar is square by cross section and one end were vertically connected cuts
The tubular vertical frame bar that face is also square is made into integration, and uses respectively in the upper end at the two ends of tubulose vertical bar and tubular vertical frame bar
Plastic cap blocks；The relative inner face of described tubular vertical frame bar is provided with indent can insert the side of insulation barrier from the top down
Connected in star.
Connection base described in the utility model can enter the upper track of inspection trolley by pulley, makes this device energy
Enough it is positioned on inspection trolley, provides cost savings；Described folding rod can be changed between two underframe bars by rotary screw
Distance, to adapt to different electric pressure switch cubicle Quarantine Tasks；The underframe bar of described device can bearing pin on folding rod
Rotate, fold up, reduce floor space；Described device uses bulk insulation barrier, can be by complete for the static contact of switch cubicle
