Description

The high voltage isolator earthing device
Technical field
The utility model relates to isolating switch, particularly a kind of high voltage isolator earthing device.
Background technology
High voltage isolator institute band earthing device is most important, if the isolating switch branch of band earthed switch, close a floodgate not in placely, gently then has influence on normal use, and serious meeting causes a serious accident.
At present, used on the market high voltage isolator earthing device mainly is divided into two parts: assembling of ground connection fixed contact and the assembling of ground connection moving contact, the assembling of ground connection fixed contact is to be fixed on through fixed block to touch on the excellent bar.Because the folding of high voltage isolator can produce very big impulsive force, so the position of ground connection fixed contact just is easy to generate change, has a strong impact on the fail safe of high voltage isolator earthing device.The ground connection moving contact directly be welded on rotating shaft on knife bar link to each other because the action of gravity of knife bar and moving contact itself, thus this earthing device when closure in order to overcome the deadweight of itself, and make given birth to the closing course time grow, the defective of the big ability of kinetic energy of consumption.Therefore, just need the novel reliable earthing device of a cover to overcome the defective of above structure, realize the function of original isolating switch branch, combined floodgate.
Summary of the invention
To structural deficiency in the prior art; The purpose of the utility model provides a kind of high voltage isolator earthing device; This device can be grounded the fixing of fixed contact and insulator, conducting rod assembling relative position, and solves earthing device and when closure, produced the big defective of kinetic energy that the closing course time is long, consume for the gravity that overcomes itself.
For realizing above-mentioned purpose; The technical scheme that the utility model adopts provides a kind of high voltage isolator earthing device; Said high voltage isolator includes welding base, insulator, conducting rod assembling, conductive clip assembling, earthing device; Said earthing device includes ground connection fixed contact, the assembling of ground connection knife bar, ground connection swivel axle, balance bracket; Wherein: said ground connection fixed contact is through being bolted between the assembling of insulator and conducting rod, and the assembling of ground connection knife bar is separately fixed on the ground connection swivel axle with balance bracket, and ground connection swivel axle directly is fixed on the welding base of isolating switch.
The beneficial effect of the utility model is to adopt this high voltage isolator earthing device; Efficiently solve the fixing of ground connection fixed contact and insulator, conducting rod assembling relative position; And solve the big defective of kinetic energy that earthing device has produced closing course time length, consumed for the gravity that overcomes itself when closure, also improved the security reliability of isolating switch.

Embodiment
In conjunction with accompanying drawing the high voltage isolator earthing device structure of the utility model is explained.
The high voltage isolator earthing device structure of the utility model is: said high voltage isolator includes welding base, insulator, conducting rod assembling, conductive clip assembling, earthing device; Said earthing device includes ground connection fixed contact, the assembling of ground connection knife bar, ground connection swivel axle, balance bracket; Said ground connection fixed contact 1 is through being bolted between the assembling of insulator and conducting rod; The assembling 2 of ground connection knife bar is separately fixed on the ground connection swivel axle 4 with balance bracket 3, and ground connection swivel axle 4 directly is fixed on the welding base of isolating switch.Described ground connection fixed contact 1 and conducting rod assembling keeping parallelism, ground connection fixed contact 1 is along with opening with closure of isolating switch rotated.
Said ground connection knife bar assembling 2, balance bracket 3 and ground connection swivel axle 4 coaxial rotatings.
As shown in Figure 1, be the whole sketch map of high voltage isolator, it comprises welding base, insulator, conducting rod assembling, conductive clip assembling, this five part of earthing device, wherein earthing device is the improved structure of the design.
As shown in Figure 2; Ground connection fixed contact 1 is through being bolted between the assembling of insulator and conducting rod; It can be along with opening with closure of isolating switch rotated; Will guarantee ground connection fixed contact 1 and conducting rod assembling keeping parallelism during installation, when isolating switch was opened, ground connection fixed contact 1 also was in and can contacts closed position with ground connection knife bar assembling 2 like this.The welding base secure fit of ground connection swivel axle 4 and isolating switch; Guaranteeing the 4 rotating whiles of ability of ground connection swivel axle; Limited it again and horizontally slipped, ground connection knife bar assembling 2 is fixed on the ground connection swivel axle 4 with balance bracket 3, and ground connection knife bar assembling 2 is done gyration around ground connection swivel axle 4 simultaneously along with the revolution of ground connection swivel axle 4; Slowly rise or slowly landing, perhaps break off with the ground connection fixed contact is closed.The balance bracket 3 that is in same horizontal level with ground connection knife bar assembling 2 also can rise or landing along with 4 revolutions of ground connection swivel axle; Owing on the balance bracket 3 balancing weight is arranged; And be positioned at the rightabout of same level with ground connection knife bar assembling 2, therefore assemble 2 when lifting when the ground connection knife bar, balance bracket 3 is in falling state; The cause of gravitional force can let earth brace assembling 2 speed when contacting with ground connection fixed contact 1 very fast, and can contact fully.This kind high voltage isolator earthing device has improved the security reliability of isolating switch greatly.
As shown in Figure 3, include a connecting plate in the ground connection fixed contact 1 with four holes, four hole sites on this connecting plate are the same with the pitch-row on the insulator, are convenient to the installation of ground connection fixed contact 1.
