Arrester installation pedestal

Technical field

The present invention relates to field of electrical equipment, specifically a kind of arrester pedestal.

Background technique

Demand with the upgrading of rural power grids since the covering of current electric power networks is increasingly wider and " 13 ", to arrester Measure it is also increasing, and since arrester replacing is more frequent, during installation, replacement and removal, need upper boom into Row operation expends great human and material resources, and high altitude operation contains some potential safety problems.

Summary of the invention

In order to solve the above technical problems, this pedestal passes through the object of the present invention is to provide a kind of installation pedestal of arrester After once mounting, the operations such as subsequent installation, replacement and removal are without repeating upper boom replacement.Specific technical solution is as follows:

Arrester installation pedestal, including high-intensitive supporting insulator 1, upper support 2, lower support 3, wiring bent plate 4, pluck Hook 10, combination contact flat spring 6, arc fingertip 7, arrester upper contact head 8, half a month axis body 9；The upper support 2, lower support 3 are separately fixed at the upper and lower ends of high-intensitive supporting insulator 1；Arc fingertip 7 is fixed on wiring bent plate 4；Wiring bent plate 4 is fixed In upper support 2；Half a month axis body 9 is arranged in the end of lower support 3, and arrester upper contact head 8 is embedded in arc fingertip 7, arrester Lower contact 13 is embedded in half a month axis body 9；The half a month axis body 9 includes linking arm 31, dislodging hook 10, pressure spring 11, elastic slice 12, described Elastic slice 12 between arc fingertip 7 at a distance from be greater than lightning arrester body length 3-10mm；31 one end of linking arm and lower support 3 are solid Fixed, dislodging hook 10 is arranged in other end；Dislodging hook 10 is embedded in elastic slice 12, and pressure spring 11 is arranged between elastic slice 12 and dislodging hook 10；It keeps away Contact 13 is abutted with elastic slice 12 under thunder device.

Another form of the half a month axis body 9 includes the contact spring that 31 lower end of linking arm is fixed on by bolt 18 15, contact 13 includes two contact arms 17 under arrester, and the contact arm 17 is connect by shaft 16 and 10 axis of dislodging hook；It is described to connect Touching reed 15 is embedded between the contact arm 17, also, the two sides of contact spring 15 are abutted with contact arm 17.

Linking arm 31 and lower support 3 are the same part, along its length with multiple bolts and high-intensitive supporting insulator 1 Lower end fix.

Arc fingertip 7 includes an arc groove 71 and a horn mouth 72, and arrester upper contact head 8 is embedded in after passing through horn mouth 72 In the arc groove 71.

Inclined-plane 73 is arranged in 7 lower end of arc fingertip.

The invention has the characteristics that:

1. the high-intensitive supporting insulator design of installation pedestal uses integrated casting, and new material carbon is added in the material Fiber and resin on the basis of not only increasing its insulation performance, significantly increase the intensity of insulator.While installation pedestal Using the high-intensitive stainless steel material for having antifouling paint, high-intensitive shock can be born and dislike supporter by making pedestal integrally above and below Bad environmental condition enhances its service life, and can avoid light pollution.

2. the arc fingertip of installation pedestal uses tin bronze, not only there is good conduction, and have excellent Elasticity, it is ensured that arrester contact can smoothly carry out division；Unique cambered design guarantee arrester contact after closure, With self-locking effect, while it ensure that reliable close contact；Fingertip outer end, which extends, simultaneously extends out formula guiding, can make to take shelter from the thunder Device can be smoothly caught in fingertip in closure.

3. the combination contact flat spring of installation pedestal is made of the high-tension pressure spring and contact of special material, when closing for arrester After conjunction, the lower connection bolt of arrester, which is caught in contact, forms pressure to contact, and contact is under the action of pressure spring, it is ensured that contact It is contacted with the reliability of bolt.

4, the half a month axis body of mounting frame is designed using special structure, guarantees axis body in the dislodging hook for being linked into half opening Afterwards, it can effectively rotate and under the action of pressure spring, dislodging hook can not be detached, guarantee the security reliability that arrester is seted out.

To sum up, the present invention solve the operations such as the installation, replacement, disassembly of arrester manpower waste and security risk this Technical problem reduces operating cost and ensure that the safety of operator.

Specific embodiment

The present invention is illustrated with reference to the accompanying drawing, as shown in Figure 1-Figure 3, arrester installation pedestal, including high-intensitive branch It supports insulator 1, upper support 2, lower support 3, wiring bent plate 4, dislodging hook 10, combination contact flat spring 6, arc fingertip 7, take shelter from the thunder Device upper contact head 8, half a month axis body 9；The upper support 2, lower support 3 are separately fixed at the upper and lower of high-intensitive supporting insulator 1 Both ends；Arc fingertip 7 is fixed on wiring bent plate 4；Wiring bent plate 4 is fixed on upper support 2；The end setting half of lower support 3 Month axis body 9, arrester upper contact head 8 are embedded in arc fingertip 7, and contact 13 is embedded in half a month axis body 9 under arrester；The half a month axis Body 9 includes linking arm 31, dislodging hook 10, pressure spring 11, elastic slice 12, the elastic slice 12 between arc fingertip 7 at a distance from be greater than it is lightning-arrest The 3-10mm of device body length；31 one end of linking arm and lower support 3 are fixed, and dislodging hook 10 is arranged in other end；Dislodging hook 10 It is embedded in elastic slice 12, pressure spring 11 is set between elastic slice 12 and dislodging hook 10；Contact 13 is abutted with elastic slice 12 under arrester.

Another form of the half a month axis body 9 is as shown in figure 4, include being fixed on 31 lower end of linking arm by bolt 18 Contact spring 15, contact 13 includes two contact arms 17 under arrester, and the contact arm 17 passes through shaft 16 and 10 axis of dislodging hook It connects；The contact spring 15 is embedded between the contact arm 17, also, the two sides of contact spring 15 are abutted with contact arm 17.

Inclined-plane 73 is arranged in 7 lower end of arc fingertip.

Application method of the invention is: when needing replacing arrester, pulling downward on dislodging hook, arrester and half with long ditch Moon axis body disengaging, falls down under gravity；When installation, contact under arrester is first embedded in half a month axis body with long ditch, then will Arrester upper contact head pushes arc fingertip to, since linking arm 31 or lower support 3 are with preferably elastic metal, and elastic slice 12 Distance L is greater than the 3-10mm of lightning arrester body length M between arc fingertip 7, which can be according to different arrester models It is adjusted；Inclined-plane 73 is arranged in 7 lower end of arc fingertip.It thus not only ensure that arrester upper contact head smoothly slides into arc fingertip In, it is ensured that the contact rigid contact up and down of arrester.
