[0002] With the development of society, in order to reduce the losses caused by power outages to users and improve power supply reliability and people's quality of life, most of the existing distribution lines are operated under live conditions during maintenance. In the prior art, for the live operation of 10kv distribution network bypass for replacing the load switch on the pole with load, when the bypass high-voltage flexible cable is connected to the bypass load switch, in order to reduce the stress on the cable joint part on both sides of the bypass load switch, the operator needs to install two temporary cable support frames to support the transition of the bypass flexible cable, so that the bypass flexible cable can be connected to the main conductor of the overhead line. The temporary cable support frame is usually temporarily installed on the pole through a clamp, which is cumbersome to operate and has a large workload. The staff spends a lot of time on the insulation wrapping operation, which increases the overall time of line maintenance and reduces work efficiency. The search publication number is (CN214899820U), which discloses an insulating support crossarm for bypass operation. The cable clamping structure of the support crossarm is open, and there is a safety hazard of cable falling off. At the same time, the connection structure between the support crossarm and the pole adopts a bolt clamping method, which does not have the convenience of quick disassembly and assembly, and needs to be improved. Therefore, we propose an insulating crossarm for bypass operation. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Embodiment 1, as Figure 1-4 As shown, the utility model provides a technical solution: an insulating crossarm for bypass operation, comprising an insulating crossarm body 1, a cable clamping mechanism 6 and a crossarm end fixing mechanism, the crossarm end fixing mechanism comprising an arc clamping cylinder 1 2 and an arc clamping cylinder 2 3 which are arranged oppositely, the arc clamping cylinder 1 2 is fixed to one end of the insulating crossarm body 1, a clamping frame 5 is fixedly arranged on both the front and rear sides of the arc clamping cylinder 2, a clamping strip 4 for clamping with the clamping frame 5 is fixedly arranged on both the front and rear sides of the arc clamping cylinder 2 3, a clamping strip 4 for clamping with the clamping frame 5 is integrally formed on the surface of the clamping strip 4 with a clamping tooth 401, the cable clamping mechanism 6 comprises a clamping seat 601, a V-shaped seat 602, a clamping rod 604, a vertical rod 605 and a clip 603, the V-shaped seat 602 is fixed to the top of the clamping seat 601, one end of the clamping rod 604 is hinged to the left side of the V-shaped seat 602, the other end of the clamping rod 604 is clamped with the right end of the V-shaped seat 602, and the vertical rod 605 runs through the middle of the clamping rod 604 and is arranged perpendicular to the clamping rod 604.

[0021] In a specific embodiment of the present utility model, the insulating cross arm 1, the arc clamp and the insulating handle 606 are all made of cross-linked polyethylene material. The cross-linked polyethylene has high voltage resistance, high heat resistance and good waterproof performance. It has high mechanical strength and can maintain stable insulation performance under high voltage environment. The surface of the insulating cross arm is coated with orange-red warning paint. The card strip 4 is made of elastic material and is offset to the outside. When the card strip 4 is inserted into the card frame 5, the elasticity of the card strip 4 makes the card tooth 401 clamped to the end face of the inner groove of the card frame 5, thereby limiting the movement of the card strip 4. The arc clamp 1 2 and the arc clamp 2 3 are embraced as a whole. When the arc clamp needs to be disassembled, it is only necessary to press the two card strips 4 inward to separate the card tooth 401 from the end face of the inner groove of the frame 5, and the card strip 4 can be directly removed from the inside of the card frame 5 to complete the separation of the arc clamp 1 2 and the arc clamp 2 3. The clamp seat 601, V-shaped seat 602, clip 603, clamp rod 604, and vertical rod 605 are all made of stainless steel, and a layer of insulating coating is coated on the surface to reduce the power conduction of the cable.

[0022] In the preferred technical solution, a through groove 607 is provided at the right end of the V-shaped seat 602, and a ball head column 608 is elastically connected to the surface of one side of the clamping rod 604. A concave hole for accommodating the ball head column 608 is provided on the surface of the clamping rod 604, and a spring is arranged in the concave hole to realize the elastic movement of the ball head column 608. A limiting groove for clamping with the clamping rod 604 is provided at the top of the right end of the V-shaped seat 602. The width of the limiting groove is 1 mm smaller than the narrow side width of the clamping rod 604. The right end of the V-shaped seat 602 is interference fitted in the limiting groove and the ball head end of the ball head column 608 is clamped in the through groove 607 at the same time, which can improve the stability of the clamping rod 604 and the V-shaped seat 602 when overlapping.

[0023] In the preferred technical solution, an arc-shaped groove is integrally formed at the bottom of the clip 603, the center line of the clip 603 is aligned with the center line of the V-shaped seat 602, and the clip 603 matches the shape of the inner cavity of the V-shaped seat 602 to facilitate clamping and fixing the cable.

[0024] In the preferred technical solution, a slot is provided at the penetration point between the clamping rod 604 and the vertical rod 605, and a rubber pad lining is provided on the inner wall of the slot for frictional contact with the vertical rod 605. The vertical rod 605 is in frictional contact with the rubber pad lining, so that the movement of the vertical rod 605 is damped, which facilitates the secure clamping of the cable.

[0025] In the preferred technical solution, an insulating handle 606 is fixedly provided at one end of the clamping rod 604, and the clamping rod 604 can be safely operated using the insulating handle 606.

[0026] Working principle: by fitting the inner wall surface of the arc clamp 1 2 with the surface of the pole, and then fitting the arc clamp 2 3 with the surface of the pole, the clamping strip 4 is inserted into the inside of the clamping frame 5 until the arc clamp 1 2 and the arc clamp 2 3 are both in contact with the surface of the pole. The elasticity of the clamping strip 4 makes the clamping tooth 401 clamped to the end face of the inner groove of the clamping frame 5, thereby limiting the movement of the clamping strip 4, unfolding the clamping rod 604 to put the cable into the V-shaped seat 602, and then clamping the clamping rod 604 and pressing down the vertical rod 605 to make the clamp 603 in close contact with the cable, so as to achieve temporary fixation of the cable.
