Background technology
The 10KV circuit overwhelming majority is delta arrangement, and A, C two-phase sideline distance that lower sandwich circuit cross-arm is entrusted are 1.2 meters.When span is greater than the 10KV circuit experience strong wind weather of 60 meters very easily there is instantaneous short circuit in A, C two-phase.
According to certain region 1 year statistics, under strong wind weather, 10KV trip-out rate obviously rises, only the first half of the year 10KV circuit trip altogether wherein show as line tripping 358 times 572 times after successful reclosing again trip, namely due to due to large span 10KV circuit phase fault.
Utility model content
The technical problems to be solved in the utility model is: a kind of anti-short circuit insulating support rod is provided, and it can keep certain distance insulation fixing by adjacent two nearer wires, has prevented phase fault under strong wind weather, has reduced accident of power supply rate.
The technical solution adopted in the utility model is: a kind of anti-short circuit insulating support rod comprises insulating bar, and insulating bar two ends are provided with buckle; Insulating bar is provided with insulating sleeve; Described buckle comprises substrate, pivot pin, supporting bracket, is provided with symmetrically the first support plate, the second support plate in substrate diameter direction; The first support plate, the second support plate are all provided with the pin-and-hole coordinating with pivot pin; On described two ends of pivot pin, be respectively equipped with the first draw-in groove, the second draw-in groove; Described pivot pin one end penetrates pin-and-hole; Supporting bracket one end is fixed on the second support plate, and the other end of supporting bracket is provided with bayonet socket; Described bayonet socket shape coordinates with the first draw-in groove; Between supporting bracket bottom and substrate, be provided with the first stage clip; Between the pin-and-hole of bayonet socket and the first support plate, be provided with the second stage clip.
Further optimize the technical program, the insulating sleeve of anti-short circuit insulating support rod is established cover at least 5 anti-pollution flashover skirts.
Further optimize the technical program, the supporting bracket of anti-short circuit insulating support rod is provided with anti-slop serrations.
The beneficial effects of the utility model are: between two different phase conductors of close together, fixing anti-short circuit insulating support rod, can keep certain distance insulation fixing two different phase conductors.While using anti-short circuit insulating support rod, push successively two buckles to two wires, can be fast by fixed two wires, insulation and anti-soil that anti-pollution flashover skirt has further strengthened anti-short circuit insulating support rod dodge ability.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
In figure, 1 insulating bar, 2 buckles, 3 insulating sleeves, 21 substrates, 22 pivot pins, 221 first draw-in grooves, 222 second draw-in grooves, 26 supporting brackets, 261 bayonet sockets, 23 first support plates, 24 second support plates, 25 pin-and-holes, 27 first stage clips, 28 second stage clips, 31 anti-pollution flashover skirts, 262 anti-slop serrations.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
The anti-short circuit insulating support rod of Fig. 1 embodiment, comprises insulating bar 1, and insulating bar 1 two ends are provided with buckle 2; Insulating bar 1 is provided with insulating sleeve 3; Described buckle 2 comprises substrate 21, pivot pin 22, supporting bracket 26, is provided with symmetrically the first support plate 23, the second support plate 24 in substrate 21 diametric(al)s; The first support plate 23, the second support plate 24 are all provided with the pin-and-hole 25 coordinating with pivot pin 22; On described 22 two ends of pivot pin, be respectively equipped with the first draw-in groove 221, the second draw-in groove 222; Described pivot pin 22 one end penetrate pin-and-hole 25; Supporting bracket 26 one end are fixed on the second support plate 24, and the other end of supporting bracket 26 is provided with bayonet socket 261; Described bayonet socket 261 shapes coordinate with the first draw-in groove 221; Between supporting bracket 26 bottoms and substrate 21, be provided with the first stage clip 27; Between the pin-and-hole 25 of bayonet socket 261 and the first support plate 23, be provided with the second stage clip 28.
While using anti-short circuit insulating support rod, first push buckle 2 to wire, supporting bracket 26 pressurizeds move downward, and the second stage clip 28 is compressed, the first draw-in groove 221 in supporting bracket 26 departs from pivot pin 25, and pivot pin 22 enters the pin-and-hole 25 of the second support plate 24 under the promotion of the first stage clip 27; Now unclasp anti-short circuit insulating support rod, supporting bracket 26 resets under the effect of the second stage clip 28, snaps in the second draw-in groove 222, and wire is locked in buckle 2.Same action is locked in another root wire in the other end buckle 2 of anti-short circuit insulating support rod.The structure of buckle 2 has realized the object fast wire being locked, and is conducive to improve installation rate and dependability.
