The disconnecting switch of remote control or remote control between high-pressure side fuse switch and high-voltage line.
Background technology
Fuse switch is fitted with step-up side, is switched as transformer frequency response, so as to Repair of Transformer
Or power consumption control.But when overhauling transformer, because the high pressure end of incoming cables of fuse switch is closer to the distance from transformer,
Security threat is produced to maintainer, so typically installing disconnecting switch in the high pressure end of incoming cables of fuse switch, ensures to become
Depressor maintainer safety.Disconnecting switch generally comprises installation channel-section steel, insulation column, enters phase connection plate, goes out phase connection plate and lead to
Electric arm, insulation column have two, and the upper end of two insulation columns is arranged on the both ends of installation channel-section steel, enters phase connection plate and goes out to connect
Line plate is respectively and fixedly installed to the lower end of insulation column, and energization arm is made up of two panels copper plate screw and spring installation, and one
Hold and go out phase connection plate and be hinged, the other end be be fixedly mounted on on phase connection plate static contact cooperate moving contact,
When closing a floodgate, between the two panels copper plate of the insertion energization arm of static contact tightly, reliable contact performance is kept.For it is automatically controlled every
For leaving, electric operation controller is additionally provided between installation channel-section steel and energization arm, controls energization arm moving contact and static contact
Switching action.But when energization arm and static contact close a floodgate, the two panels copper plate of energization arm has very big clamping to static contact
Power, frictional force when dividing between the two, closing a floodgate is very big, and the thrust or pulling force of electric operation controller tend not to overcome the frictional force
Reliable operation is realized, causes to close between energization arm and static contact not in place, prevents latch hook with tapered end from mutually locking cooperation,
Combined floodgate poor reliability.
The content of the invention
The purpose of the present invention is the problem of presence for prior art, there is provided a kind of to keep between static contact and moving contact
In the case that clamping force is constant, can effectively reduce divide between the two, combined floodgate frictional force, ensure the reliable separating brake of electric operation controller or
Close a floodgate the electric isolating switch with rolling switch device manipulated.
Technical scheme includes installation channel-section steel, insulated column, enters phase connection plate, goes out phase connection plate, energization arm and electricity
Device is controlled, insulated column there are two, and the upper end of two insulated columns is separately mounted to install the both ends of channel-section steel, enters phase connection plate and goes out phase
Terminal plate is respectively and fixedly installed to the lower end of two insulated columns, enters on phase connection plate and static contact is fixedly mounted, and energization arm is by two panels
Copper plate is hinged by bolt and nut and spring installation composition, one end with going out phase connection plate, static contact and the energization arm other end
Elastic connection between two panels copper plate, static contact are copper plate；Electric control gear is made up of motor and control lever, and motor is fixedly mounted
In the middle part of installation channel-section steel, control lever in energization arm and is entered between phase connection plate to be provided between motor control axle and energization arm
The latch hook and tapered end of mutual cooperation；Rolling switch device is provided with mainly on phase connection plate is entered, the rolling switch device is by solid
Dingan County is mounted in into the stainless steel plate on phase connection plate and two roller compositions, stainless steel plate installation parallel with static contact, stainless steel
The width of plate is less than the width of static contact copper plate, and two rollers are arranged on stainless steel plate lower end width side by central shaft respectively
To both sides, the ultimate range between two roller excircles is more than the width of static contact copper plate.
In above technical scheme, stainless steel plate overlaps installation with the copper plate of static contact.
Roll device for spreading it is an advantage of the invention that being provided with phase connection plate is entered, during combined floodgate, roller first with energization arm
Two panels copper plate between be in rolling contact, the two panels copper plate of energization arm is rolled through roller and static contact clamped contact, subtract
The small frictional force of switch closing and switch opening process, closing moment is reduced, ensures to close between energization arm and static contact under electronic manipulation
In place, latch hook is made reliably to be locked with tapered end, it is ensured that combined floodgate reliability.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
Electric isolating switch with rolling switch device as shown in Figure 1, including channel-section steel 9, insulated column 11 are installed, enter phase
Terminal plate 12, go out phase connection plate 8, energization arm 3 and electric control gear, installation channel-section steel 9 is fixedly mounted on high-pressure column, and insulated column 11 is adopted
With high-tension porcelain insulator, insulated column 11 has two, and the upper end of two insulated columns 11 is separately mounted to install the both ends of channel-section steel 9, enters to connect
Line plate 12 and go out the lower end that phase connection plate 8 is respectively and fixedly installed to two insulated columns 11, enter on phase connection plate 12 to be fixedly mounted quiet
Contact 2, static contact 2 are copper plate, and energization arm 3 is made up of two panels copper plate bolt and nut and the installation of spring 4, and spring 4 is pacified
Between nut and the wherein a piece of copper plate of energization arm 3, the one end of energization arm 3 is be hinged with going out phase connection plate 8, makes energization arm 3
It can be rotated around the pin joint, elastic connection between the two panels copper plate of static contact 2 and the other end of energization arm 3；Electric control gear is by electricity
Machine 10 and control lever 7 form, and motor 10 is fixedly mounted on the middle part of installation channel-section steel 9, and control lever 7 is located at the control shaft of motor 10 with being powered
