Abstract
The utility model provides a kind of cable accessory, and the cable accessory is simple in construction, reliability is high.The cable accessory includes cable accessory terminal and fixing device, the fixing device is used to fix cable accessory terminal on the line, fixing device includes support insulator and/or arrester, and the lower end of support insulator and/or arrester is fixedly connected by fixing fitting with the lower end of cable accessory terminal.The cable accessory is due to being additionally arranged the fixing device for fixing cable accessory terminal, greatly improve the stability of shrinking prefabricated cable fitting terminal, cost is significantly reduced relative to composite sheath or porcelain overcoat oil-filling type cable accessory terminal simultaneously, and reliability is very high.
Description
Technical field
The utility model belongs to median and high voltage power system application field, and in particular to a kind of cable accessory.
Background technology
At present, cable accessory terminal is connected with electric line, generally from following two cable accessory terminals：
1st, composite sheath or porcelain overcoat oil-filling type cable accessory terminal
When the cable accessory terminal is installed at the scene, influenceed larger by environmental factor (such as air humidity, filth), especially
Insulating oil easily pollutes during oiling, or product tilts insulating oil and overflowed, and causes the reduction of product insulating properties, influences its safety
Operational reliability.
2nd, shrinking prefabricated cable fitting terminal
The cable accessory terminal is flexible structure, is difficult to fix on the line, is put by such environmental effects such as wind-force
It is dynamic, it is easily caused alternate or mutually and terra short.
Both the above structure, the normal operation to power system brings very big potential safety hazard.Meanwhile, cable accessory is whole
Arrester is not installed at end, and under the over-voltage conditions such as thunderbolt, operation, the insulation safety of cable accessory terminal can not be guaranteed,
Operational reliability is lower.Therefore, need badly and provide a kind of simple in construction, reliability high cable accessory.
The content of the invention
The problem of in order to solve in the presence of background technology, the utility model provides a kind of cable accessory, the cable accessory
Simple in construction, reliability is high.
Technical solution of the present utility model is as follows：
The cable accessory includes cable accessory terminal and fixing device, and the fixing device is used to consolidate cable accessory terminal
Fixed fixing device includes support insulator and/or arrester on the line, and the lower end of support insulator and/or arrester passes through
Fixing fitting is fixedly connected with the lower end of cable accessory terminal.
It is preferred that, the upper end of support insulator and/or arrester passes through metal connecting piece and the high pressure of cable accessory terminal
End is fixed and electrically connects.
It is preferred that, fixing fitting can be integrally formed, by cable accessory terminal, support insulator and/or arrester
Be fixed, as entirety integral piece when, it is desirable to be processed and formed at one time, such reliability is higher.
It is preferred that, the fixing fitting is provided with the fixed plate of U-type groove, and the lower end of cable accessory terminal is caught in U-type groove
It is fixed afterwards by anchor ear.
The utility model has the advantage of：
It is pre- that the cable accessory improves shrinkage due to being additionally arranged the fixing device for fixing cable accessory terminal, greatly
The stability of standard cable annex terminal, while greatly being dropped relative to composite sheath or porcelain overcoat oil-filling type cable accessory terminal
Low cost, and reliability is very high.
Especially when fixing device includes arrester, arrester is not only able to protect the insulation safety of cable accessory terminal
Not by being struck by lightning, the overvoltage such as operate to be damaged, also improve the stability and reliability of cable accessory terminal operating.
Brief description of the drawings
Fig. 1 is the utility model structural upright schematic diagram；
Fig. 2 is the utility model structural front view；
Accompanying drawing is detailed as follows：
1- cable accessory terminals；2- fixing devices；3- fixing fittings；4- metal connecting pieces.
Embodiment
The principle of the utility model institute foundation is：By increasing fixing device to shrinking prefabricated cable fitting terminal, with
The influence for avoiding environment from producing it.In the selection of fixing device, preferred arrester, arrester enters to cable accessory terminal
While row is fixed, moreover it is possible to the overvoltage such as protect its insulation safety not by being struck by lightning, operate damaged.
The utility model is described in detail below in conjunction with accompanying drawing, as shown in Figure 1：
The cable accessory includes cable accessory terminal and fixing device, and fixing device is used to cable accessory terminal being fixed on
On circuit.Fixing device can choose the device of various types and structure, and shrinkage prefabricated cable can be avoided in principle
Annex terminal causes alternate or mutually and terra short to occur under the extreme weathers such as strong wind because rocking.It is preferred that fixing device is pillar
Insulator or arrester, wherein optimal with arrester.
The lower end of fixing device (i.e. support insulator and/or arrester) passes through under fixing fitting and cable accessory terminal
End is fixedly connected, and fixing fitting can be integrally formed, and cable accessory terminal, support insulator or arrester are consolidated
It is fixed, several parts can also be made, cable accessory terminal, support insulator or arrester are fixed respectively.Wherein fix
Annex in fixed plate to be provided with U-type groove, and the lower end of cable accessory terminal is caught in the knot being fixed after U-type groove by anchor ear
Structure is optimal, it would however also be possible to employ screwed hole is opened up in fixed plate or other modes are fixed.
The upper end of fixing device (i.e. support insulator or arrester) also can by way of fixing fitting by its own with
Cable accessory terminal is connected, but supports required because the bonding strength of lower end fixing fitting has been able to meet, therefore in view of letter
Change structure and reduce whole product gross weight, can use and metal connecting piece and electricity are set in the upper end of support insulator or arrester
The high-pressure side of cable fittings terminal is fixed and electrically connected.
Claims (4)
1. a kind of cable accessory, including cable accessory terminal, it is characterised in that：Also include fixing device, the fixing device is used
