Abstract
The present invention discloses a kind of outdoor AC high-voltage disconnecting switch, including insulation bogie, and three conducting rods are set on the insulation bogie；The insulation bogie is driven by rotating mechanism and rotated；Each phase of three-phase high-voltage isolating switch is respectively equipped with an insulating base, and the insulating base is respectively arranged at two ends with contact base, and groove is provided with the middle part of the contact base, sets electric shock plate, conducting rod and electric shock plate grafting in the contact base；Mounting flange is provided with the middle part of the insulating base, the insulating base of three-phase is linked together with mounting flange by installing plate.It is an advantage of the invention that：Using sheet electric shock plate, contact area is increased, it is ensured that contact is good, additionally, there is provided guide pad, is not only convenient for the insertion of conducting rod, it is often more important that, isolate insulating base and conducting rod, it is therefore prevented that damage of the heat that electric discharge is produced to insulating base.
Description
Technical field
The present invention relates to field of electrical equipment, specifically a kind of disconnecting switch.
Background technology
In power equipment, disconnecting switch consumption is huge, and its effect is reliably to separate high voltage power supply, it is ensured that operation
The safety of personnel.Chinese Patent Application No. 201010232722.1 discloses a kind of novel pole type three-phase high-voltage isolating switch,
The every of disconnecting switch is mutually provided with an insulating sleeve, for supporting the conducting element of the contact base at disconnecting switch the two poles of the earth；Insulating cylinder
Centre have mounting flange, by fixed disconnecting switch, and the two poles of the earth that disconnecting switch is switched are separated by installing plate；Conducting rod
In insulating cylinder axially inside telemechanical, for the two poles of the earth of open or closed disconnecting switch, the axial movement of conducting rod relies on one
Bogie is insulated to provide；Contact between conducting rod and contact base uses coil component spring conducting ring, by the compression of conducting ring
Deformation is come to providing contact between dynamic/static contact.But the patent is using the conducting rod of slidingtype contact, by the transversal of insulating base
Area effect, its contact area is smaller, and in particular by spring-ring type inserting contact, contact of the conducting rod with contact is linear contact lay, because
This, easily comes in contact bad and electric discharge phenomena.
The content of the invention
In order to solve the above technical problems, contacting well and being not susceptible to electric discharge phenomena it is an object of the invention to provide a kind of
Disconnecting switch, concrete scheme is as follows：
A kind of outdoor AC high-voltage disconnecting switch, including insulation bogie, set three conductions on the insulation bogie
Bar；The insulation bogie is driven by rotating mechanism and rotated；Each phase of three-phase high-voltage isolating switch is respectively equipped with an insulation
Seat, the insulating base is respectively arranged at two ends with contact base, is provided with groove in the middle part of the contact base, is set in the contact base and touched
Electroplax, conducting rod and electric shock plate grafting；Mounting flange is provided with the middle part of the insulating base, by installing plate and mounting flange by three
The insulating base of phase links together；The medium position of the insulating base set with multiple guide pads of the outer diameter contact of conducting rod with
Prevent damage of the heat that electric discharge is produced to insulating base；Insulation bogie rotarily drive conducting rod radially with the grafting of electric shock plate
Or separate, so as to realize the conducting of electric current and disconnect.
The insulation bogie outer layer sets insulating barrier, internal integral with conducting rod.
It is an advantage of the invention that：Using sheet electric shock plate, contact area is increased, it is ensured that contact is good, additionally, setting
Guide pad, is not only convenient for the insertion of conducting rod, it is often more important that, isolate insulating base and conducting rod, it is therefore prevented that electric discharge is produced
Damage of the heat to insulating base.
Brief description of the drawings
Fig. 1 is structural representation of the invention；
Fig. 2 is schematic top plan view.
Specific embodiment
The present invention is illustrated below in conjunction with the accompanying drawings, and as shown in Figure 1 and Figure 2, the present invention includes insulation bogie 1, described exhausted
Three conducting rods 6 are set on edge bogie；The insulation bogie 1 is driven by rotating mechanism and rotated；Three-phase high-voltage isolating switch
Each phase be respectively equipped with an insulating base 8, the insulating base 8 is respectively arranged at two ends with contact base 4, in the contact base 4
Portion is provided with groove, and electric shock plate 5, conducting rod 6 and the grafting of electric shock plate 5 are set in the contact base 4；It is provided with the middle part of the insulating base
Mounting flange, is linked together the insulating base 8 of three-phase with mounting flange by installing plate 7.
The medium position of the insulating base 8 sets the multiple guide pads 3 with the outer diameter contact of conducting rod 6.
The insulation bogie outer layer sets insulating barrier, internal integral with conducting rod, such as using the method or whole of welding
The modes such as body casting.
The whirligig can use current techique, such as artificial or motor-driven whirligig.
Principle of the invention is：Whirligig drives insulation bogie 1 to rotate, and then with moving conductive rod 6 and electric shock plate 5
Grafting or separation, so as to realize the conducting of electric current and disconnect.
