Accompanying drawing explanation
The structural representation that accompanying drawing 1 is arrester device of the present utility model.
In above accompanying drawing: 1, anti-slip support; 11, left end frame; 12, right-hand member frame; 13, connecting plate; 2, overvoltage protection device; 3, ball discharge; 4, lightning stroke counter; 5, insulator; 6, counter installing hole.
Embodiment
Below in conjunction with embodiment shown in the drawings, the utility model is further described.
Embodiment mono-: shown in accompanying drawing 1.An arrester device, it comprises anti-slip support 1 on the cross-arm that is installed on shaft tower, be installed on overvoltage protection device 2 on anti-slip support 1, be relatively installed on overvoltage protection device 2 and anti-slip support 1 and coaxial and have a fixed range a pair of ball discharge 3, be fixedly arranged on lightning stroke counter 4 on anti-slip support 1, be installed on the insulator 5 on anti-slip support 1.
Anti-slip support 1 comprises left end frame 11, right-hand member frame 12 and the connecting plate 13 that connects left end frame 11 and right-hand member frame 12.
On right-hand member frame 12, offer the protector installing hole of overvoltage protection device 2 and the location hole that overvoltage protection device 2 is positioned are installed, overvoltage protection device 2 is installed on right-hand member frame 12 and by location hole and is positioned by protector installing hole.The diameter of protector installing hole is 11-17mm, and the diameter of location hole is 3-7mm.The copper conductor connecting on overvoltage protection device 2 is connected in transmission and distribution network.
On connecting plate 13, offer two counter installing holes 6, lightning stroke counter 4 is installed on connecting plate 13 by the bolt of these two counter installing holes 6 and coupling.Lightning stroke counter 4 is connected with the ball discharge 3 on anti-slip support 1, it comprises inductance probe, the electric capacity being connected with inductance probe, the electromagnetism dial-type counter being connected with electric capacity, with the resistance of Capacitance parallel connection, be connected with electromagnetism dial-type counter and there is the controller of display unit (display screen); One end of inductance probe is connected with the ball discharge 3 on anti-slip support 1 by copper conductor, and the other end is connected with anti-slip support 1 and ground connection.
Because the installation of lightning stroke counter 4 need to; make the length of connecting plate 13 longer; and then make the distance being installed between a pair of ball discharge 3 on anti-slip support 1 and overvoltage protection device 2 be greater than the fixed range that it need to keep; therefore consider increases by a carrier to shorten two distances between ball discharge 3 in arrester device, and this distance is met design requirement.Therefore an insulator 5 is installed on anti-slip support 1, the ball discharge 3 on anti-slip support 1 is installed on insulator 5.Concrete; on left end frame 11, offer installing insulating 5 and also can vertically adjust the sparking electrode installing hole of the position of insulator 5; insulator 5 is installed on left end frame 11 by this sparking electrode installing hole; the one end that is insulator 5 is connected with anti-slip support 1; ball discharge 3 is installed on the other end of insulator 5 and ball discharge 3 on overvoltage protection device 2, and keeps specific distance between two ball discharges 3.
In addition, also offer the arc opening slot on the cross-arm that is installed on shaft tower on left end frame 11, the diameter of this arc opening slot is 10-23mm.Owing to being the opening slot of arc, so installation is quite convenient.
Above-mentioned arrester device is when the normal operating conditions without thunderbolt, and its inside does not almost have electric current to pass through.And when there is thunderbolt, the ball discharge 3 that lightning current just can have rapidly the ball discharge 3 on overvoltage protection device 2 to flow through on insulator 5, and then flow into lightning stroke counter 4, finally imports undergroundly, lightning stroke counter 4 forms cascaded structures with overvoltage protection device 2.When lightning current is flowed through lightning stroke counter 4, inductance probe gathers lightning current signals, and its electric capacity completes once and discharges and recharges, and drives electromagnetism dial-type counter to carry out record, and the display unit by controller demonstrates number of lightning strokes.Yet most of electric current, from slipping away with the resistance of Capacitance parallel connection, makes the voltage of electric capacity be limited by resistance, and electric capacity can not broken yet.
The advantage of above-mentioned arrester device is:
(1) can record number of lightning strokes, and be presented on the display screen of lightning stroke counter 4;
(2) because lightning stroke counter 4 is connected with overvoltage protection device 2, by lightning stroke counter 4, can also know the ruuning situation of overvoltage protection device 2, and can, according to the size of leakage current, judge the operating efficiency of overvoltage protection device 2;
