Description

Technical Field

[0001] The invention relates to the technical field of installation devices for disconnecting switches, and in particular to a fixing bracket for disconnecting switches. Background Art

[0002] When a traditional isolating switch is installed on a pole, it is directly installed horizontally or vertically on the two cross arms of the pole. This installation method makes the isolating switch vertical or parallel to the ground.

[0003] When the isolating switch is vertical to the ground, it is difficult and requires a lot of effort for the operator to disconnect the isolating switch using the operating rod on the ground; it is also difficult and requires a lot of effort to close the isolating switch, which may cause poor contact at the joints for a long time and burn out the isolating switch; when the isolating switch is parallel to the ground, it is difficult to operate when the operator disconnects the isolating switch using the operating rod on the ground because there are often lightning arresters and other equipment at the bottom of the isolating switch and the operating space is small; when the isolating switch is closed, it may also cause failure to close the switch.

[0004] In addition, the traditional installation method of isolating switches does not fix the upper leads of the isolating switches. Under various conditions such as daily wind, rain, and the electric force generated by the wires, the upper leads of the isolating switches are prone to breakage. After the upper leads are broken, they are connected to the crossarm by the wind, causing a grounding fault in the line. Summary of the invention

[0005] The present invention provides an isolating switch fixing bracket to solve the problem that the existing isolating switch is installed horizontally or vertically, which makes it inconvenient to operate the isolating switch during conventional operations such as disconnecting and closing.

[0006] In order to achieve the above invention purpose, the technical means adopted are:

[0007] A disconnect switch fixing bracket comprises a mounting plate, a first fixing bracket and a second fixing bracket; one end of the first fixing bracket is connected to a side surface of the mounting plate at an acute angle; the other end of the second fixing bracket is fixedly connected to a support; one end of the second fixing bracket is connected to a side surface of the mounting plate at an acute angle; the other end of the first fixing bracket is fixedly connected to a support.

[0008] In the above scheme, the other end of the first fixing bracket and the other end of the second fixing bracket are respectively fixedly connected to the cross arm, and then the isolating switch is connected and fixed to the other side of the mounting plate to complete the installation of the isolating switch. Since one end of the first fixing bracket and one end of the second fixing bracket are respectively connected to one side of the mounting plate at an acute angle, the isolating switch is also installed at a certain angle to the vertical direction after being fixed.

[0009] Preferably, the mounting plate is an L-shaped mounting plate, and through holes are provided on both the horizontal side and the vertical side of the L-shaped mounting plate. In this preferred embodiment, the insulator can be fixedly connected to the L-shaped mounting plate through the through holes on the horizontal side, and the disconnector can be fixedly connected to the L-shaped mounting plate through the through holes on the vertical side.

[0010] Preferably, the first fixing frame includes two fixing strips connected to each other, one end of the first fixing frame is fixedly connected to one side of the vertical side of the L-shaped mounting plate at an acute angle, and the other end of the first fixing frame is fixedly connected to the support; the second fixing frame includes two fixing strips connected to each other, one end of the second fixing frame is fixedly connected to one side of the vertical side of the L-shaped mounting plate at an acute angle, and the other end of the second fixing frame is fixedly connected to the support.

[0011] Preferably, the other end of the first fixing frame is also fixedly connected to the first bottom plate, and the first bottom plate is provided with a first through hole; the other end of the second fixing frame is also fixedly connected to the second bottom plate, and the second bottom plate is provided with a second through hole. In this preferred solution, the first fixing frame and the second fixing frame are respectively fixed to the two cross arms through the first bottom plate and the second bottom plate, so that they are more firm and easier to operate.

[0012] Preferably, the two fixing bars of the first fixing frame are connected by a fixed connection method, and the two fixing bars are integrally formed with each other; the two fixing bars of the second fixing frame are connected by a fixed connection method, and the two fixing bars are integrally formed with each other.

[0013] Preferably, the two fixing bars of the first fixing frame are connected to each other through a hinge device with a locking structure, and the two fixing bars of the second fixing frame are connected to each other through a hinge device with a locking structure. In this preferred solution, the two fixing bars are fixed by providing a hinge device with a locking structure, so that the angle between the two fixing bars can be adjusted according to actual needs, thereby adjusting the angle of the disconnector after being fixed, and then the state can be locked by the locking structure.

[0014] Preferably, one end of the first fixing bracket is fixedly connected to one side of the vertical side of the L-shaped mounting plate at an angle of 60°, and one end of the second fixing bracket is fixedly connected to one side of the vertical side of the L-shaped mounting plate at an angle of 60°. In this preferred solution, since the fixing bracket is installed at an angle of 60° to one side of the vertical side of the L-shaped mounting plate, that is, the isolating switch is installed at an angle of 60° to the vertical direction after being fixed, and the work of measuring the distance between the two cross arms during the installation process is reduced.

[0015] Preferably, one end of the first fixing bracket is fixedly connected to one side of the vertical side of the L-shaped mounting plate at an angle of 45°, and one end of the second fixing bracket is fixedly connected to one side of the vertical side of the L-shaped mounting plate at an angle of 45°. In this preferred solution, since the fixing bracket is installed at an angle of 45° to one side of the vertical side of the L-shaped mounting plate, that is, the disconnector is installed at an angle of 60° to the vertical direction after being fixed, and the work of measuring the distance between the two cross arms during the installation process is reduced.

[0016] Preferably, the mounting plate, the first fixing frame and the second fixing frame are respectively a mounting plate made of SMC material, a first fixing frame made of SMC material and a second fixing frame made of SMC material. In this preferred solution, SMC integrated molding technology is adopted, and the original hardware and ceramic insulators are replaced with SMC materials, which saves construction time; at the same time, SMC materials have high mechanical strength and good insulation performance, are not easy to age, and can not only realize the function of fixing the traditional disconnector, but also have a long service life.

[0017] Compared with the prior art, the technical solution of the present invention has the following beneficial effects:

[0018] In the present invention, since one end of the first fixing bracket and the second fixing bracket are connected to one side of the vertical side of the L-shaped mounting plate at an acute angle, the isolating switch installed on the L-shaped mounting plate is also installed at a certain angle to the vertical direction after being fixed, and the angle can be adjusted according to actual needs, thereby solving the problem that the existing isolating switch installation method is horizontal installation or vertical installation, which makes it inconvenient to operate the isolating switch during routine operations such as disconnecting and closing. At the same time, the horizontal side of the L-shaped mounting plate of the present invention is used to install insulators, and the insulators are used to fix the upper leads of the isolating switch, thereby reducing the occurrence of broken leads on the isolating switch, thereby reducing the occurrence of line failures. In addition, the isolating switch fixing bracket is made of SMC integrated molding technology, and the original hardware and ceramic insulators are replaced by SMC materials, which saves construction time; and because the SMC material has high mechanical strength and good insulation performance, the service life of the product is extended.
