Embodiment 1

[0034] refer to Figure 1~6 , providing a schematic diagram of the overall structure of a 0.4kV line phase-to-phase anti-collision device, as shown in figure 1 , a 0.4kV line phase-to-phase anti-collision device includes a rotating unit 100 that allows some parts of the device to rotate, a bearing unit 200 that carries the rotating unit 100, an adjusting unit 300 and a limit unit 400, and an adjusting unit that regulates the device 300. The limiting unit 400 for limiting the rotating unit, the first rotating shaft 101 for rotating the rotating unit 100, and the first limiting block 102 for limiting the first rotating shaft 101, when the lines are arranged in rows , no need to change the shape of the device, let the line pass through the rotating unit 100, the carrying unit 200 and the adjusting unit 300, the limit unit 400 will limit the position of the rotating unit 100, so as to solve the problem of excessive sag of the 0.4kV line under the influence of wind and external for...

Embodiment 2

[0042] refer to figure 2 , this embodiment is different from the first embodiment in that: the rotating unit 100 for rotating some parts of the device includes a first rotating shaft 101 for rotating the rotating unit 100, and a first rotating shaft 101 for limiting the first rotating shaft 101. The limit block 102, the first installation block 103 enabling the first support rod 104 to be installed, the first support rod 104 for supporting, the support block 105 for supporting the adjustment unit 300, and the accommodation for the adjustment unit 300 The circular arc groove 106, the first through hole 107 to limit the circuit, the accommodation space N1, the ring mounting block 101-1 that allows the limit tooth 101-2 to be installed, and the limit to the first rotating shaft 101 The limiting tooth 101-2, when the circuit is arranged in a row, without changing the shape of the device, the circuit passes through the first through hole 107 in the rotating unit 100, the carrying ...

Embodiment 3

[0051] refer to figure 2 , This embodiment is different from the above embodiments in that: the carrying unit 200 carrying the rotating unit 100, the adjusting unit 300 and the limiting unit 400 includes a housing 201 that protects the device, and a first circuit that limits the circuit. The limit hole 202 and the second limit hole 203 that limit the adjustment unit 300, when the lines are arranged in rows, there is no need to change the shape of the device, so that the lines pass through the first through hole 107 in the rotation unit 100, the carrying unit 200 The first limit hole 202 and the adjustment unit 300 in the center, the limit unit 400 limits the rotation unit 100, so as to solve the problem that the sag of the 0.4kV line is too large, and the wire with a low sag will be entangled under the action of wind and external force Together, the low-voltage line is short-circuited, the voltage rises, and the problem of burning out the user's equipment occurs.

Abstract

The invention discloses a 0.4kV line phase-to-phase anti-collision device. The anti-collision device includes a rotating unit, a bearing unit, an adjusting unit and a limit unit. The rotating unit includes a first rotating shaft and two The first limit block at the end, the bearing unit, is fixedly connected with the rotation unit through the first limit block, and the adjustment unit is connected with the load unit through a bearing shaft; and the limit unit is fixed with the inner wall of the first limit block through the first The block is fixedly connected; the present invention separates the lines through the mutual cooperation among the rotating unit, the carrying unit, the adjusting unit and the limit unit, so as to ensure that the lines will not appear due to the excessive sag of the lines, under the influence of wind and external forces. Under the action, the wires with lower sag will be entangled together, thereby further avoiding the short circuit of the low-voltage line, the voltage rise, and the burning of user equipment, ensuring the reliability of power supply and improving customer satisfaction.

Description

technical field [0001] The invention relates to the technical field of circuit protection devices, in particular to a 0.4kV line phase-to-phase anti-collision device. Background technique [0002] In recent years, due to issues such as land coordination, the original 0.4kV poles of the low-voltage power supply network cannot completely follow the standard span of 50 meters to erect a base pole, resulting in many cases where the span of low-voltage lines exceeds 100 meters, or even reaches 200 meters. As a result, the 0.4kV line sag is too large, and the wires with low sag will be entangled under the action of wind and external force, resulting in a short circuit of the low-voltage line, a rise in voltage, and burnout of user equipment. As a result, the winding of the transformer heats up, causing the transformer to fail, expanding the scope of power outages, reducing the reliability of power supply, and affecting customer satisfaction. Contents of the invention [0003] T...
