[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Embodiment 1

[0025] like Figure 1 - Figure 3 As shown, a disconnector contact protection device comprises a protective sleeve 1 and a hole 11 arranged on the protective sleeve 1, a positioner 2 is symmetrically mounted on the protective sleeve 1, a driving spring 21 is fixedly mounted inside the positioner 2, a support plate 22 is arranged inside the positioner 2, and one end of the driving spring 21 is fixedly connected to the outer wall of the support plate 22, a connecting block 221 is fixedly mounted on the support plate 22, and an insulating block 222 is fixedly mounted on the connecting block 221. When the disconnector contact protection device is used to protect the disconnector contact, the protective sleeve 1 is sleeved on the disconnector contact, thereby To protect the contacts of the isolating switch, after the protective cover 1 is put on the contact, the elasticity of the driving spring 21 itself will push the support plate 22 to move. When the support plate 22 moves, it will push the connecting block 221 to move, and then drive the insulating block 222 to contact one side of the contact, and then the position of the locator 2 will be limited by the connecting block 221, and then the position of the protective cover 1 will be limited, so as to improve the stability of the installation of the isolating switch contact protection device and avoid the sliding of the position of the isolating switch contact protection device during use to affect the protection effect. The insulating block 222 is made of rubber.

[0026] Furthermore, a limiting groove 23 corresponding to the connecting block 221 is fixedly installed inside the positioner 2, and the connecting block 221 is penetrated inside the limiting groove 23, and the limiting groove 23 facilitates the position of the connecting block 221 to slide.

[0027] Embodiment 2

[0028] like Figure 1 , Figure 4 and Figure 5As shown, a contact protection device for an isolating switch proposed in the present invention is another implementation mode of the present invention compared to the first embodiment. A box body 3 is fixedly installed on the top of the protective cover 1. The box body 3 is rectangular in shape, and the protective cover 1 provides an installation space for the box body 3.

[0029] Furthermore, an array of vent holes 31 is provided on the box body 3, and a filter is provided inside the vent holes 31. When the outside air enters the inside of the box body 3 through the vent holes 31, the filter can filter and purify the flowing air.

[0030] Furthermore, a micro fan 32 is symmetrically installed inside the box 3, a battery assembly 34 is fixedly installed inside the box 3, and the battery assembly 34 is electrically connected to the micro fan 32, and an array of jet holes 331 is arranged on the flow groove 33. The battery assembly 34 provides power for the micro fan 32 to operate, and the micro fan 32 will extract air from the inside of the box 3 when it operates.

[0031] Furthermore, the protective cover 1 is symmetrically provided with flow grooves 33, and the output end of the micro fan 32 is connected to the flow grooves 33. The air drawn by the micro fan 32 will flow into the flow grooves 33. When the air flows in the flow grooves 33, it will flow to the contact surface below through the jet holes 331, thereby removing the adsorbed matter on the contact surface of the isolating switch, thereby facilitating the cleaning of the isolating switch contacts and preventing the adsorbed matter from being adsorbed on the isolating switch contacts, thereby affecting the service life.

[0032] Working principle: When using this type of isolating switch contact protection device, first, when using the isolating switch contact protection device to protect the isolating switch contacts, the protective cover 1 is put on the isolating switch contacts to protect the isolating switch contacts. After the protective cover 1 is put on the contact, the elasticity of the driving spring 21 itself will push the support plate 22 to move. When the support plate 22 moves, it will push the connecting block 221 to move, and then drive the insulating block 222 to contact one side of the contact, and then the position of the locator 2 will be limited by the connecting block 221, and then the position of the protective cover 1 will be limited, so as to improve the stability of the installation of the isolating switch contact protection device and avoid the position sliding of the isolating switch contact protection device during use to affect the protection effect.

[0033] Finally, the air drawn by the micro fan 32 will flow into the interior of the flow groove 33. When the air flows in the interior of the flow groove 33, it will flow to the contact surface below through the jet hole 331, and then the adsorbent on the surface of the isolating switch contact can be removed, thereby facilitating the cleaning of the isolating switch contacts and avoiding the adsorbent from being adsorbed on the isolating switch contacts, which affects the service life.

[0034] This is the working principle of the contact protection device of the isolating switch.
