Description
Technical field
It the utility model is related to electrical equipment technical field, and in particular to block switch masking device on a kind of column.
Background technology
Power distribution automation is the new technology that recent years, fast development was got up, and is the inexorable trend of distribution modernization.With
The continuous lifting of distribution automation coverage rate, common fuse switch, isolation switch etc. are cut-offfing equipment just in traditional distribution
Gradually substituted by novel intelligent on-pole switch.
Intelligent on-pole switch is broadly divided into block switch according to purposes and user demarcation switchs two kinds, can according to arc quenching method
To be divided into two kinds of patterns of pvs (pole-mounted vacuum switch) and pole-mounted circuit breaker, according to the outlet mode of connection can be divided into flexible cable outlet and
Binding post pattern.
At present, the block switch applied to distribution line backbone is mainly the vacuum on-pole switch of binding post pattern, it
Field demand is adapted to, the mode of connection is flexible, and through-current capability is strong, and cost is moderate, thus is widely applied.
Block switch plays very important effect in network operation.It carries all electric currents of back end of line, and
And according to the instruction of electrical power distribution automatization system, play the role of isolated fault section.Its importance is self-evident.
But block switch also exposes some problems in operative practice in recent years, most important is exactly binding post
Fever.Mainly block switch through-flow larger and duration the reason for fever is grown, and will cause once binding post crimping is bad
Fever.The fever harm of block switch binding post is larger, and such as processing would be possible to the power failure for causing large area not in time, influence to produce
Life.
The processing of binding post fever generally has two ways, power failure mode and the mode that do not have a power failure.Using power failure mode need by
Whole line outage, operating personnel, which is stepped on after bar eliminates defect, recovers power transmission.The mode of uninterrupted operation is taken, insulation bucket need to be utilized
The carrying tool such as arm car or insulated platform carries out defect elimination using insulating glove method.Increasing the present is required in power supply reliability
My god, the unsuitable use of power failure operation mode.It is mostly to use uninterrupted operation mode defect elimination in practice, is needed in operation
Electrical body at operating point and grounding body are all covered, trigger danger to prevent operating personnel from touching different potentials object by mistake
Danger.And existing insulation masking apparatus is universal instrument, use relatively complicated, danger coefficient is higher, is easily sent out
Hot object scald is scrapped.Thus a set of specific purpose tool is urgently developed to reduce work risk, ensures job safety.
Utility model content

The one side connection of plate one, the another side of insulation board one are fixed with two insulation and hook, on the insulation board one positioned at insulation board two and
Position between insulation board three is equipped with fluting one, the position of three side of 21 side position of insulation board and insulation board is equipped with fluting two,
There is fluting three on the insulation board four.
Further, the insulation board one, insulation board two, insulation board three and insulation board four use rigid insulation resin plate.
Further, the fluting one, fluting two and fluting three are respectively provided with straight slot and flaring groove section, the straight slot one
Hold and tilted for semicircular arc structure, other end connection flaring groove section, the groove inner wall of the flaring groove section with the axis of fluting in one
Determine angle, i.e. the width of flaring groove section end is more than the width of straight slot.
Further, the straight slot width of the fluting one is equal to the outside diameter of block switch bushing outer surface card slot on column,
Fluting one can be clamped in the card slot of bushing outer surface, and three straight slot width of the fluting two and fluting are more than block switch on column
The outside diameter of bushing outer surface card slot, not only improves fluting two and fluting three is easily caught in block switch bushing outer surface on column
In card slot, and the difficulty of processing of fluting two and fluting three is reduced, the length of the fluting can make fluting bottom surface with being opened on column
When closing the card slot contact of casing, the electrical body and ground connection body portion of block switch on the completely obscured column of insulation board.
Further, the insulation hooks installation site and the switch handle position of block switch on column matches, and has 90 °
Bending structure, the bending structure can hooking live the switch handle of block switch on column.
The beneficial effects of the utility model：
Block switch on the column of the utility model, simple in structure, manufacture cost is low, and when use can effectively cover to be segmented on column
Switch, allows operating personnel to avoid direct contact with electrical body, and related isolation work can be completed only near conducting wire, is kept away at the same time
Instrument caused by having exempted from contact heating body is scalded, and operating personnel's activity space is larger in work, and dielectric strength is big, and security is more
It is high.
