The utility model good effect is as follows:
The utility model comprises insulator support portion, the first lightning protection portion, the second lightning protection portion and scarer, discharge counter and lightning arrester are designed to one, for recording the action frequency of lightning arrester, reliable data are provided in time to the running quality of lightning arrester, the generation of Accident prevention, improve the reliability of power system operation, high resistance body is high performance metal-oxide resistor disc, there is good nonlinear wind vibration, striking head is isolated from the outside by high resistance body, improve fail safe, add electric discharge sensitiveness simultaneously, striking is effective, when there is thunderbolt, the electric charge that striking head gathers can promptly discharge, ensure that the safety of insulated cable and terminal equipment, in addition, by adjusting the bolt on the second support, the distance between striking head and puncture striking head can be changed, its distance size adjusts according to environment for use, moist foggy and heavy pollution regional should discharging gap bigger than normal, the regional discharging gap of dry low filth can be less than normal, in addition, striking head is also conveniently replaced, be convenient to installation and maintenance, the bottom of described first puncture folder and the second puncture folder is respectively arranged with a meter puncture tooth for lattice shape layout, this kind of structure makes puncture dental transition easily puncture into the insulating barrier of wire, and the damage reduced wire, puncture tooth do not established by the puncture folder be positioned at above wire, therefore the top that when wire is stressed, stress is larger is not damaged, and prevents the reduction of wire stretch-proof intensity, during use, in normal state, high resistance body and discharging gap are failure to actuate, only exceed regulation lightning overvoltage when occurring, discharging gap could be breakdown, forms short-channel, release overvoltage energy, avoids burn with guardwire, after voltage release, high resistance body recovers high resistance, gap discharge stops, and in addition, described first puncture folder and the second the outer of puncture folder are provided with insulating sheath, make puncture folder and puncture striking head are wrapped in the inside by insulating cover, ensure that and run the safety in using, because China's transmission overhead line operates in field mostly, be not easy the monitoring being subject to manpower in time, therefore the impact by birds activity is larger, described scarer is salmon pink, rely on wind drive, the rotation of its quick different directions constantly can send the reverberation of interval, to interference and the scaring of birds vision, reaches effect on driving birds.
Accompanying drawing explanation
Fig. 1 is the utility model overall structure schematic diagram.
In accompanying drawing, 1 insulator, 2 first puncture folders, 3 first supports, 4 second supports, 5 counters, 6 high resistance bodies, 7 striking heads, 8 second puncture folders, 9 puncture striking heads, 10 rotating shafts, 11 connecting rods, 12 reflection shields, 13 puncture teeth.
Embodiment
As shown in Figure 1, the technical solution of the utility model comprises insulator support portion, the first lightning protection portion, the second lightning protection portion and scarer; Described insulator support portion comprises insulator 1, first puncture folder 2 and the first support 3, and described insulator 1 top is provided with the first puncture folder 2, and described insulator bottom is provided with the first support 3.
Described first lightning protection portion comprises the second support 4, counter 5, high resistance body 6 and striking 7, described second support 4 is fixed on the first support 3, described counter 5 is arranged on the bottom of high resistance body 6, discharge counter and lightning arrester are designed to one, for recording the action frequency of lightning arrester, reliable data are provided in time to the running quality of lightning arrester, the generation of Accident prevention, improve the reliability of power system operation, described high resistance body 6 is bolted on the second support 4, high resistance body 6 is high performance metal-oxide resistor disc, there is good nonlinear wind vibration, striking head is isolated from the outside by high resistance body, improve fail safe, add electric discharge sensitiveness simultaneously, striking is effective, when there is thunderbolt, the electric charge that striking head gathers can promptly discharge, ensure that the safety of insulated cable and terminal equipment, in addition, by adjusting the bolt on the second support 4, the distance between striking 7 and puncture striking 9 can be changed, its distance size adjusts according to environment for use, moist foggy and heavy pollution regional should discharging gap bigger than normal, the regional discharging gap of dry low filth can be less than normal, thus, striking 7 is conveniently replaced, be convenient to installation and maintenance, described striking 7 is arranged on high resistance body 6 top, counter 5, be electrical connection between high resistance body 6 and striking 7,
