Lightning-arrest mechanism comprises:
First link of zinc oxide arrester 22 is provided with moving contact 5, and the lateral surface of described upper moving contact 5 is provided with outwards flat insulation of stretching and operates ring 51 and side arm 52; Described side arm 52 can snap in described pressure mouth 14, thus makes moving contact 5 be fixed on upper static contact 4;
Preferably, described insulation operation ring 51 and described side arm 52 are symmetricly set in the both sides of the lateral surface of moving contact 5.
Second link dockingundocking device 8 of zinc oxide arrester 22, one end that disconnector 8 is not connected with described second link is provided with bracing wire 81.
Preferably, described bracing wire 81 can be copper cash.
Lower moving contact 9 is fixed on the insulated porcelain sleeve 6 of zinc oxide arrester 22 by support 7; Preferably, the hoop 71 of described support 7 is arranged on insulated porcelain sleeve 6, near the side of the second link of zinc oxide arrester 22;
As shown in Figure 2, lower moving contact 9 is fixed with spring pressuring plate 91, the bracing wire 81 on disconnector 8 is tightened after pressing through the loose one end of spring pressuring plate 91 and is fixed on a set bolt 92 of lower moving contact 9; Lower moving contact 9 is also provided with fixed axis 93; Described fixed axis 93 can be hung on the described mounting mouth 151 of lower fixed contact 15.
Preferably, can stablize to make fixed axis 93 and be hung on the described mounting mouth 151 of lower fixed contact 15, described lower fixed contact 15 can be the hollow box not going up bottom surface and leading flank, wherein two relative sides are arranged respectively mounting mouth 151, fixed axis 93 penetrates lower moving contact 9, be positioned at the both sides of lower moving contact 9, thus the part that fixed axis 93 is positioned at the both sides of lower moving contact 9 is articulated on a mounting mouth 151 respectively, makes described mounting more reliable and stable.
Preferably, as shown in Figure 2, described lower moving contact 9 and the tie point 94 of support 7 are positioned at the rearward end of lower moving contact 9, and lower moving contact 9 is positioned at the middle part of lower moving contact 9 with the tie point 95 of spring pressuring plate 91, and the fixed axis 93 of lower moving contact 9 is positioned at the leading section of lower moving contact 9; Described set bolt 92 is positioned on the lateral surface of the leading section of lower moving contact 9.Wherein, the shape of described lower moving contact 9 can be D shape as shown in Figure 2, or other shapes, does not limit here.
Preferably, as shown in Figure 1, described upper static contact 4 can be fixed on the upper end of insulator 12 by bolt and hoop, and high-voltage terminal 3 is still fixed on the upper end of insulator 12 by bolt and hoop, described bolt first passes bolt hole corresponding on upper static contact again through high-voltage terminal 3, thus high-voltage terminal 3 and upper static contact 4 is fixed on simultaneously the upper end of insulator 12;
Same, as shown in Figure 1, described lower fixed contact 15 can be fixed on the lower end of insulator 12 by bolt and hoop, and earth terminal 16 is still fixed on the lower end of insulator 12 by bolt and hoop, described bolt first passes bolt hole corresponding on lower fixed contact 15 again through earth terminal 16, thus earth terminal 16 and lower fixed contact 15 is fixed on simultaneously the lower end of insulator 12.
The lightning arrester operation principle of above-mentioned the embodiment of the present application is described as follows:
As shown in Figure 3, be the normal operating conditions of the embodiment of the present application lightning arrester, wherein, the fixed axis 93 of described lower moving contact 9 is hung on the described mounting mouth 151 of lower fixed contact 15; The described side arm 52 that upper moving contact 5 is arranged snaps in described pressure mouth 14, thus moving contact 5 is fixed on upper static contact 4.Thus insulated fixing support 1 and lightning-arrest mechanism 2 can be with the use of, realize lightning protection function.
As shown in Figure 4, when the zinc oxide arrester 22 in the embodiment of the present application lightning arrester because of fault damage or breakdown or earial drainage time, disconnector 8 is fused gradually, splits away off from the second link of zinc oxide arrester 22, hangs in the air by bracing wire 81; And, because bracing wire 81 is no longer tightened, thus the spring pressuring plate 91 on lower moving contact 9 produces elastic force effect, this elastic force effect passes to side arm 52 place by zinc oxide arrester 22, side arm 52 is hauled out from pressure mouth 41, lightning-arrest mechanism 2 is still hung on lower fixed contact 15 by the fixed axis 93 on lower moving contact 9, but the embodiment of the present application lightning arrester can not work, and could continue normal work after needing again to change lightning-arrest mechanism 2.Described disconnector 8 can be set to redness, will more easily make user find the lightning arrester broken down like this.
Because lightning arrester described in the embodiment of the present application is when lightning-arrest mechanism-trouble, lightning-arrest mechanism splits away off from the upper static contact of insulated fixing support, but still hang on lower fixed contact, thus lightning arrester described in the embodiment of the present application also can be called drop-type arrester.
When carrying out lightning-arrest mechanism 2 and changing, as long as old lightning-arrest mechanism 2 is taken off from the mounting mouth 151 of lower fixed contact 15 by the insulation operation ring in old lightning-arrest mechanism 2, by the insulation operation ring in new lightning-arrest mechanism 2, the fixed axis 93 in new lightning-arrest mechanism 2 is hung on the mounting mouth 151 of lower fixed contact 15, again the side arm 52 of new lightning-arrest mechanism 2 is pushed pressure mouth 14, it is convenient to change.
Give the reference dimension of mounting panel 11 and the embodiment of the present application lightning arrester in FIG, but and be not used in the restriction carrying out mounting panel 11 size and the embodiment of the present application lightning arrester size, in actual applications, independently can set the size of mounting panel 11 and the embodiment of the present application lightning arrester, not limit here.The unit of sized data described in Fig. 1 is: mm.
The above is only the preferred implementation of the application; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the application's principle; can also make some improvements and modifications, these improvements and modifications also should be considered as the protection range of the application.
