Description

Technical Field

[0001] The utility model relates to a 6kV trolley switch operating handle. Background Art

[0002] Many 6kV switches in thermal power plants are floor-standing. The trolley switch itself weighs more than 300 kilograms and has a high voltage level. To ensure the personal safety of operators, when the trolley switch stops supplying power, operators need to wear insulating gloves and use the trolley switch operating handle to swing in and out. Because the trolley switch weighs 300 kilograms and the trolley operating handle is not designed properly, the operating handle is often entangled by the insulating gloves when the operator is operating. It is necessary to stop and rearrange the insulating gloves before continuing to operate. Similar operations must be repeated 3 times each time to complete.

[0003] During the operation, when you stop to adjust the insulating gloves, the moving and static contacts of the trolley switch have not yet fully contacted, and there is a risk of discharge from the 6kV high-voltage bus to the moving trolley contacts, posing a great threat to the personal safety of the operating personnel.

[0004] In summary, there is no solution in the prior art for using a 6kV switch to stop power supply. Utility Model Content

[0005] The utility model is to solve the above-mentioned technical problems and provides a 6kV trolley switch operating handle.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A 6kV trolley switch operating handle, comprising an "X"-shaped handle, a fixed grip of the "X"-shaped handle is sleeved with a handle sleeve, and a force grip of the "X"-shaped handle is sleeved with a rotating sleeve;

[0008] The rotating sleeve comprises a long sleeve and two symmetrically arranged jackets which are clamped and fixed on the fixed handle, and the two jackets are rotatably connected to the long sleeve.

[0009] The 6kV trolley switch operating handle, the sleeve includes an inner ring and an outer ring, the inner ring and the outer ring are connected by fixing bolts, and a plurality of spheres arranged in a circle are clamped between the inner ring and the outer ring.

[0010] The 6kV trolley switch operating handle has sliding grooves on the inner ring walls at both ends of the long sleeve. Beneficial Effects

[0011] 1. The utility model is provided with a handle sleeve on the fixed grip of the U-shaped handle, and a rotating sleeve is sleeved on the force-applying grip of the U-shaped handle, ensuring that the operating personnel can operate the 6kV high-voltage electrical switch in place at one time while wearing insulating gloves, and ensuring the personal safety of the operating personnel.

[0012] 2. When the operating personnel of the utility model operate, it is simple and quick, greatly reducing the workload of the operating personnel in operating the 6kV high-voltage switch.

[0013] 3. The rotating sleeve of the utility model includes a long sleeve and two symmetrically arranged clamping sleeves clamped and fixed on the fixed grip. The position of the long sleeve can be limited through the clamping sleeves. While ensuring its rotation effect, it can prevent the long sleeve from moving in position when applying force during operation and contacting the two ends of the force-applying grip, resulting in excessive friction and affecting its operation.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] Reference Figures 1 - 2 , a 6kV trolley switch operating handle, which comprises a J-shaped handle 1. A handle sleeve 3 is sleeved on the fixed grip 4 of the J-shaped handle, and a rotating sleeve 2 is sleeved at the force-applying grip 5 of the J-shaped handle;

[0026] The rotating sleeve includes a long sleeve 22 and two symmetrically arranged clamping sleeves 21 clamped and fixed on the fixed grip. The two clamping sleeves are rotatably connected to the long sleeve.

[0027] During operation, hold the rotating sleeve on the force-applying grip with one hand and hold the handle sleeve on the fixed grip with the other hand. In this way, when the handle is rotated, the rotating sleeve can rotate relative to the handle, and the handle sleeve can rotate relative to the handle, effectively preventing the insulating gloves from getting entangled.

[0028] Reference Figures 3 - 7 , the clamping sleeve includes an inner sleeve ring 213 and an outer sleeve ring 212. Both the inner sleeve ring and the outer sleeve ring are formed by buckling semi-circular sleeve rings. The upper half of the outer sleeve ring is fixedly connected to the upper half of the inner sleeve ring through a fixing bolt. An annular groove 214 is opened at the end near the upper half of the outer sleeve ring and the upper half of the inner sleeve ring. Put the sphere into the annular groove of the inner sleeve ring, and then buckle the outer sleeve ring to clamp the sphere. The connection form between the lower half of the outer sleeve ring and the lower half of the inner sleeve ring is the same as that of the upper half. After connection, the upper half and the lower half are respectively buckled on the force-applying grip, and then the clamping sleeve is fixed through a clamping bolt 215. The inner sleeve ring is connected to the outer sleeve ring through a fixing bolt 211, and a plurality of spheres 23 arranged in a circumferential manner are clamped between the inner sleeve ring and the outer sleeve ring.

[0029] Reference Figures 8 - 10 , annular grooves 222 are opened on the inner wall of both ends of the long sleeve. This annular groove is an annular slot. The long sleeve is formed by buckling two semi-circular sleeves 221 and fixedly connected through a locking bolt 223. Half-ring grooves are respectively opened at both ends of each semi-circular sleeve. After the two semi-circular sleeves are buckled, a complete annular groove is formed. This annular groove corresponds to the position of the sphere. After the long sleeve is fixed, a part of the sphere of the clamping sleeve at both ends is located in the annular groove, which can achieve the smoothness of the rotation of the long sleeve and limit the position of the long sleeve to prevent its position from shifting.
