Detailed description of the invention
Below in conjunction with the accompanying drawings embodiment of the present utility model is illustrated.
Fig. 1 is the structural representation of the drop-type arrester according to embodiment one of the present utility model；This reality according to Fig. 2
Partial sectional view with the first conductive seat of the drop-type arrester of new embodiment one；Fig. 3 is to implement according to this utility model
The structural representation of the second conductive seat of the drop-type arrester of example one.As shown in Fig. 1 to Fig. 3, this drop-type arrester 100 wraps
Include insulator 101.This insulator 101 is preferably ceramic insulator or composite insulator.This insulator 101 can be by the band at middle part
Hole sheet 101a is arranged on electric pole or other positions to be installed.
This drop-type arrester 100 also includes rainhat 103.The upper end phase of the left end of rainhat 103 and insulator 101
Connect, and in rainhat 103, be provided with the conductive member 106 of band draw-in groove.This drop-type arrester 100 also includes falling device 104.Should
Fall device 104 and include the first conductive seat 104a of band hook and slot 1401 and the second conductive seat 104b of band peg 1402.Wherein, described
Hook and slot 1401 and peg 1402 belong to well known to those skilled in the art, are not described in detail at this.First conductive seat 104a with
The lower end of insulator 101 is connected, and is provided with arc guide groove 104c, sets on the second conductive seat 104b on the first conductive seat 104a
There is guide protrusions 104d matched with arc guide groove 104c.
This drop-type arrester 100 also includes the spark gap main body 102 being connected with the second conductive seat 104b.This spark gap master
Body 102 is hung in the hook and slot 1401 of the first conductive seat 104a by the peg 1402 of the second conductive seat 104b so that spark gap master
Body 102 can carry out rotation up and down relative to insulator 101.Wherein, it is positioned at extreme higher position when spark gap main body 102
Time, the draw-in groove phase clamping of the upper end of spark gap main body 102 and conductive member 106, guide protrusions 104d is positioned at arc guide groove
104c；When spark gap main body 102 turns to extreme lower position, guide protrusions 104d skids off arc guide groove 104c, to allow
The peg 1402 of two conductive seat 104b departs from the hook and slot 1401 of the first conductive seat 104a；When spark gap main body 102 is in highest order
When putting the position rotation between extreme lower position, guide protrusions 104d is always positioned in arc guide groove 104c, to stop second
The peg 1402 of conductive seat 104b departs from the hook and slot 1401 of the first conductive seat 104a.In this way, this utility model
Drop-type arrester 100 by the arc guide groove 104c being fitted to each other and guide protrusions 104d, it is ensured that spark gap master
Body 102 departs from insulator 101 in damaging falling process the most on one's own initiative, thus avoids spark gap main body 102 to inadvertently fall off and pound
Hurt sb.'s feelings or thing.
Preferably, this rainhat 103 is integral type structure, and has inversion type U-shaped portion 103a and two lamellars are led
To portion 103b, the most each lamellar guide part 103b, right-hand member with corresponding reversed formula U-shaped portion 103a is connected below respectively.Inversion type U
The left end of type portion 103a is connected with the upper end of insulator 101, and this conductive member 106 is located in inversion type U-shaped portion 103a.When lightning-arrest
When device main body 102 is rotated up relative to insulator 101, the lamellar at rainhat 103 is guided by the upper end of spark gap main body 102
Enter in rainhat 103 under the guiding function of portion 103b, until the upper end of spark gap main body 102 and the draw-in groove of conductive member 6
Till phase clamping.Traditional rainhat and guiding fork are united two into one by this rainhat 103, can not only ensure drop-type arrester
The rainhat 103 of 100 has guide function, also can simplify assembly technology, thus be prone to improve production efficiency.
In summary, drop-type arrester 100 of the present utility model by the arc guide groove 104c being fitted to each other and is led
To protruding 104d, it is ensured that spark gap main body 102 departs from insulator 101 in damaging falling process the most on one's own initiative, thus keeps away
Exempt from spark gap main body 102 to inadvertently fall off and injure people or thing by a crashing object.
