Problems solved by technology

[0004] The existing switch cabinet emergency opening button remote control operation device only acts on the emergency opening button, does not provide a solution for rotating the knob, and cannot realize the closing operation. When using it, the pressing function of the emergency opening button is realized by remote control
Therefore, the existing switch cabinet emergency opening button remote control device cannot be applied to the knob type on-site opening and closing switch and the knob + push type on-site opening and closing switch
At present, there is no auxiliary device that can safely and quickly complete the remote control operation of the knob when the original remote control fails.

Embodiment 1

[0026] Embodiment one: if figure 1 As shown, the knob clamping device for remote operation of the switch cabinet includes two matching positioning blocks 10, the positioning block 10 is a rectangular block, and the positioning block 10 is used to clamp the key 13 of the knob switch without a handle. Positioning blocks 10 are respectively provided with positioning bases 7 on the side facing away from each other, and guide rods 11 are respectively fixed on the sides where the two positioning bases 7 are far away from each other. There is a guide hole 12 that cooperates with the guide rod 11, the guide rod 11 passes through the guide hole 12, the two sides of the support seat 5 and the two positioning bases 7 are provided with threaded rods 6, and the two sides of the threaded rods 6 are respectively provided with opposite rotation directions. The two screw threads with opposite directions are matched with the two positioning bases 7 respectively. By turning the threaded rod 6, ...

Embodiment 2

[0030] Embodiment 2: The upper and lower sides of the support base 5 are respectively pierced with clamping rods 4, and the opposite ends of the clamping rods 4 are respectively provided with clamping blocks 3; the support base 5 is provided with a spirit level 9, which is available on the market; other and Embodiment 1 is the same.

[0031] This embodiment is suitable for knobs with handles, and the positioning block 10 has a "冂"-shaped structure, which can better cooperate with the knobs. At the same time, it cooperates with the clamping rod 4 and the clamping block 3 to realize the clamping and fixing of the knob handle.

[0032] When the present invention is made, make with light insulating material. When in use, cooperate with the remote control device, the remote control device pushes the extension rod 8 through the electric telescopic rod, so as to realize the rotation of the key on the knob with handle or the knob without handle, thereby completely remote control.

Abstract

The invention discloses a knob clamping device for remote operation of a switch cabinet, and belongs to the technical field of auxiliary devices for remote operation of high-voltage switch cabinets. The device mainly comprises two matched positioning blocks, positioning bases are arranged on the sides, deviating from each other, of the two positioning blocks respectively, guide rods are arranged on the two positioning bases respectively, supporting seats are arranged on the outer sides of the positioning bases, guide holes matched with the guide rods are formed in the supporting seats, threaded rods are arranged on the two sides of the supporting seats and the two positioning bases in a penetrating mode, and the threaded rods are connected with the guide rods. The two sides of the threaded rod are provided with threads opposite in screwing direction respectively, and the two threads opposite in screwing direction are matched with the two positioning bases respectively. The clamping device is suitable for clamping the on-site opening and closing switch with the knob, so that the clamping device is matched with a remote control device, accurate control over the on-site opening and closing knob is achieved, and safety and reliability are achieved. The clamping device is mainly used for clamping the knob switch.

Description

technical field [0001] The invention belongs to the technical field of auxiliary devices for remote operation of high-voltage switch cabinets, and in particular relates to a knob clamping device for remote operation of switch cabinets. Background technique [0002] The "Regulations on the Management of Power Substation Operation and Maintenance of the State Grid Corporation" clearly stipulates that local operations are strictly prohibited for circuit breaker shutdown and power transmission, but with the expansion of the grid scale, the number of switchgears continues to increase, and remote operation failures occur from time to time. When the remote control operation of the high-voltage switchgear fails, the existing method is to disconnect the superior switch first, and then perform the opening and closing operations on the spot. This method will lead to the expansion of the power outage range and the serious increase of the power outage time, which not only greatly increas...
