The bonding spring is C type elastic construction to behind the cabinet, the vortex can be do not not formed at the normal during operation of generating line, vortex heat radiation phenomenon has been avoided. The utility model has the advantages of the contact is reliable, and three -section structure adapts to axial deviation automatically, and sealed reliable, the no vortex generates heat, need not other earth connection, and the installation is convenient with the dismantlement, be applicable to the cabinet generating line connection within a definite time of middling pressure inflation switch cabinet.
Description
[technical field]
The utility model relates to high-voltage electrical equipment technical field, particularly relates to a kind of earthing of casing type bus connecting device.
[background technology]
Middle pressure gas-filling cabinet is used for transmission and the control of electric energy, and stainless steel Pneumatic box body inside is furnished with master switch facility, adopts bus connecting device to carry out bus expansion between cabinet.
And middle its bus-bars conductor of pressure gas-filling cabinet bus connecting device is integral structure at present, when there is skew or decentraction in switch cabinet bus position, both sides, both sides contact is uneven, contact resistance is caused to increase, during long-term energising, bus position generates heat, and acceleration insulating barrier is aging, and then causes bus connecting device generation ablation or insulation fault.The earth connection of middle its external insulation layer of pressure gas-filling cabinet bus connecting device is manual coiling at present simultaneously, and need during cabinet first earth connection to be arranged on the ground stud of side cabinet, afterwards again by another side switch cubicle near and tight, but often there is installation personnel and forget that installation earth connection is just also tight by cabinet, repeated removal can be caused like this, sometimes installation personnel just uneasy attaching ground wire, the charge inducing on insulating barrier can be caused like this to accumulate, cause the insulating case insulation breakdown of bus connecting device, cause whole electric power system fault.Therefore be necessary to provide a kind of earthing of casing type bus connecting device to solve the problem.
[utility model content]
The purpose of this utility model is to provide a kind of a kind of earthing of casing type bus connecting device being applicable to middle pressure gas-filling cabinet, this device has the feature of the casing shielding ground connection automatically adapting to axial deviation and automatically realize bus connecting device, easy for installation, reliability is high.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of earthing of casing type bus connecting device, comprise the bonding conductor being installed on insulating case inside, the both sides of bonding conductor are connected to fingertip, and the periphery of fingertip adds holds spring tightly; The shell of insulating case is provided with bonding spring.
The utility model further improves and is:
Described bonding spring and cabinet after with left cabinet side plate and right cabinet side plate reliable contacts, realize the casing shielding ground connection of bus connecting device.
And cabinet time, left and right two fingertips of insulating case inside contact respectively with the bus contact in the bus contact in left cabinet bus-bar insulator and right cabinet bus-bar insulator respectively, and two fingertips contacts with bonding conductor again simultaneously, the bus UNICOM of formation left/right cabinet.
Left and right two fingertips of described insulating case inside and bonding conductor form the syndeton of syllogic.
Described bonding spring adopts can not form eddy current when bus normally works, and avoids the open type elastic construction of eddy-current heating phenomenon.
Compared with prior art, the utility model has following beneficial effect:
In the middle of the utility model adopts, bonding conductor is connected the movable connection method of fingertip with both sides, and three stage structure can adapt to axial deviation automatically, makes contact between fingertip and cabinet reliable.The bus being applicable to middle pressure gas-filling cabinet connects.The utility model bonding spring is C type elastic construction, and bonding spring after cabinet outside insulating case automatically and cabinet side plate reliable contacts, and realize the casing shielding ground connection of bus connecting device, easy for installation, ground connection is reliable.Simultaneously because bonding spring is C type elastic construction, can not eddy current be formed when bus normally works, avoid eddy-current heating phenomenon.The bus being applicable to middle pressure gas-filling cabinet connects.
[accompanying drawing explanation]
Fig. 1 is front view of the present utility model;
Fig. 2 be the utility model and cabinet install after structural representation;
Wherein, 1 is insulating case; 2 is bonding spring; 3 is bonding conductor; 4 is fingertip; 5 for holding spring tightly; 6 is left cabinet bus-bar insulator; 7 is left cabinet side plate; 8 is right cabinet side plate; 9 is right cabinet bus-bar insulator.
[embodiment]
Below in conjunction with accompanying drawing, the utility model is described further.
See Fig. 1 to Fig. 2, the utility model comprises the bonding conductor 3 being installed on insulating case 1 inside, and the both sides of bonding conductor 3 are connected with fingertip 4, and the periphery of fingertip 4 adds holds spring 5 tightly; The bonding spring 2 that simultaneously shell of insulating case 1 is installed be the elastic construction of C type open type, and after cabinet bonding spring 2 is automatically and left cabinet side plate 7 and right cabinet side plate 8 reliable contacts.
The course of work of the present utility model and principle:
Bus connecting portion between the cabinet that the utility model is arranged on middle pressure gas-filling cabinet, is communicated with for the bus between cabinet.When also cabinet bus connects needs, first the utility model is inserted in left cabinet bus-bar insulator 6, afterwards again by another side switch cubicle near and tight, a now left side for insulating case 1 inside, right two fingertip 4 both sides contact respectively with the bus contact in the bus contact in left cabinet bus-bar insulator 6 and right cabinet bus-bar insulator 9, left, right two fingertips 4 contact with bonding conductor 3 again simultaneously, formed left, the bus UNICOM of right cabinet, the periphery of fingertip 4 adds and holds spring 5 tightly simultaneously, radial enclasping force can be formed, make contact reliable, left, right two fingertips 4 and bonding conductor 3 form the syndeton of syllogic, can deflect among a small circle in radial direction, automatic adaptation axial deviation, make contact between fingertip and cabinet reliable.
The bonding spring 2 that the shell of insulating case 1 is installed be C type elastic construction, and after cabinet, bonding spring 2 automatically and left cabinet side plate 7 and right cabinet side plate 8 reliable contacts, realizes the casing shielding ground connection of bus connecting device.Simultaneously because bonding spring 2 is C type elastic construction, can not eddy current be formed when bus normally works, avoid eddy-current heating phenomenon.
Although be below described embodiment of the present utility model by reference to the accompanying drawings, the utility model is not limited to above-mentioned specific embodiments, and above-mentioned specific embodiments is only schematic, guiding, instead of restrictive.Those of ordinary skill in the art is under the enlightenment of this specification, and when not departing from the scope that the utility model claim is protected, can also make a variety of forms, these all belong to the row of the protection of the utility model claims.
