Abstract
The utility model discloses an outdoor high-voltage isolating switch, which is mainly provided with a base, wherein a first insulating column and a second insulating column are arranged on the base; a conductive switch blade is arranged on the upper part of each insulating column, and a linkage mechanism is arranged on the lower part of each insulating column; a column shaft is arranged at the bottom of each insulating column; a shaft sleeve is arranged on the column shaft; a tile seat is arranged on the outer wall of the shaft sleeve; the upper and lower ends of the tile seat are respectively provided with a rust-proof gasket; and each-phase switch blade of the conductive switch blade consists of two conductive sheets; springs are arranged outside two sides of each conductive sheet; a contact pressure required by turning on and turning off the conductive switch blade can be obtained by adjusting the height of each spring; and a pulling ring is arranged on the conductive switch blade. Because the pulling ring is arranged on the conductive sheet, switching-on operation can be performed more safely and conveniently. Because the tile seat is formed by pressure injection of outdoor epoxy resin, the outdoor high-voltage isolating switch has high corrosion resistance capacity, high outdoor ultraviolet resistance capacity, high outdoor ageing resistance capacity, high hydrophobicity and high insulation self-recovery capacity, is attractive in appearance, simple in structure, safe and reliable, and convenient to assemble and disassemble and does not damage equipment.
Description
Technical field
The utility model relates to a kind of electric power equipment, relates in particular to a kind of easy to use, practical, safe and reliable outdoor high-voltage isolating switch.
Background technology
Isolating switch is to use maximum a kind of electrical equipment in the high-voltage switch electric appliance in power plant and the transformer station's electrical system; As its name suggests, in circuit, play buffer action, need and the supporting use of primary cut-out; The operation principle of itself and relatively simple for structure; But because use amount is big, functional reliability requires high, and is all bigger to the influence of design, foundation and the safe operation of electric substation, power plant.
Its major function is: guarantee High-Voltage Electrical Appliances and the safety of device when service work, play isolation voltage.
Existing isolating switch is in operation and all can finds the fingertip scaling loss in the maintenance annual spring and autumn; The scaling loss position is around the fingertip anchor point, and especially fingertip is terminal, and its reason is that the isolating switch combined floodgate is untimely; And; The width of contact is greater than the width of fingertip seat, and the back fingertip that closes a floodgate is strutted, and makes fingertip become line with the fingertip seat and contacts.
The utility model content
In view of this, the purpose of the utility model provides a kind of outdoor high-voltage isolating switch easy to use, practical, safe and reliable.
The technical scheme of the utility model realizes with following method,
A kind of outdoor high-voltage isolating switch mainly is provided with pedestal, and pedestal is provided with first insulation column and second insulation column; Two insulation column tops are provided with the conduction plug-in strip, and the bottom is provided with interlinked mechanism, and the bottom of each insulation column is provided with boom shaft; Boom shaft is provided with axle sleeve, and the axle sleeve outer wall is provided with a watt seat, and watt seat top and bottom are equipped with antirust packing ring; Every phase plug-in strip of conduction plug-in strip is made up of two conducting strips, and conducting strip is equipped with spring outside the both sides, and the height of regulating spring can obtain the needed contact pressure of switches conductive plug-in strip; Wherein, conducting strip is provided with draw ring, uses draw ring can carry out closing operation.
Watt seat adopts the outdoor epoxy resin injection molding of external Imported High-performance, and the ability of very high corrosion-resistant and outdoor anti-ultraviolet aging is arranged, and hydrophobicity is good, and the insulation automatic recovery ability is strong, good looking appearance, the creepage requirement that can satisfy IV level gradation for surface pollution than distance.
Pedestal is a channel-section steel, pedestal lower end ground connection.
The good effect of the utility model technical scheme is:
Because the conducting strip of the utility model is provided with draw ring, makes closing operation safer and simpler, also because a watt seat adopts outdoor epoxy resin injection molding; The ability that very high corrosion-resistant and outdoor anti-ultraviolet aging is arranged; Hydrophobicity is good, and the insulation automatic recovery ability is strong, good looking appearance; Creepage than apart from can satisfying the requirement of IV level gradation for surface pollution, the utility model is simple in structure, do not damage equipment, safe and reliable, easy installation and removal.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the structural representation of insulation column among Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
Can find out this outdoor high-voltage isolating switch, a kind of outdoor high-voltage isolating switch by Fig. 1 and Fig. 2; Mainly be provided with pedestal 1, pedestal 1 is provided with first insulation column 2 and second insulation column, 3, two insulation column tops are provided with conduction plug-in strip 7; The bottom is provided with interlinked mechanism 8, and the bottom of each insulation column is provided with boom shaft 4, and boom shaft 4 is provided with axle sleeve 5; Axle sleeve 5 outer walls are provided with watt seat 6, and watt seat 6 top and bottom are equipped with antirust packing ring 9.Every phase plug-in strip of conduction plug-in strip 7 is become by two conducting strips, and conducting strip is equipped with spring outside the both sides, and the height of regulating spring can obtain switches conductive plug-in strip 7 needed contact pressures.Wherein, conducting strip is provided with draw ring 10, uses draw ring 10 can carry out closing operation.
It can also be seen that by Fig. 1 pedestal 1 is a channel-section steel, pedestal 1 lower end ground connection.
