Description
Technical Field
The utility model relates to a contact replacer for a central switch cabinet.
Background
The central high-voltage switch cabinet is one of the high-voltage power distribution devices widely used at present, and is mainly used for power transmission of a generator and starting operation of a high-voltage motor. In the use of the middle-set high-voltage switch cabinet, in order to ensure the safety of electricity, the middle-set high-voltage switch cabinet needs to be maintained and overhauled regularly.
However, when the current transformer in the cable chamber of the central high-voltage switch cabinet is repaired or replaced, the lower contact of the switch cabinet needs to be disassembled and assembled firstly. In the prior art, the disassembly tool is usually used to directly perform the close-range disassembly. However, since the upper head of the stationary contact is provided with high voltage electricity, and the space in the central switch cabinet is limited, when the central switch cabinet is directly disassembled and assembled by using a disassembling tool, the safety distance of high voltage operation cannot be ensured, which does not meet the regulations in the national grid company electric power safety work regulations. Therefore, when the disassembly operation is carried out, the insulation rubber mat is only paved in the high-voltage cabinet, and the operators wear the insulation mode of the insulation gloves and the insulation boots to ensure the personal safety.
However, since the insulating gloves, the insulating boots and the insulating rubber pads belong to auxiliary insulating tools, the metal parts in the cabinet cannot be completely covered, and the human body cannot be completely covered, the safety of operators cannot be fundamentally guaranteed by the existing method, and serious personal casualty accidents are easy to happen. Also, it takes a lot of time, time and labor to manually wear and lay these auxiliary insulating tools. Moreover, these auxiliary insulating tools are consumable items, which are not cost effective.

Detailed Description
The utility model is described below with reference to the accompanying drawings.
Fig. 1 shows a contact replacer 100 for a central-type switchgear cabinet according to the utility model. As shown in fig. 1, the contact replacer 100 for a central-type switchgear comprises a main body 10, wherein the main body 10 is in the shape of a rod, which may be configured as a round rod or a square rod, for example. Since the middle-mounted switch cabinet contacts are provided with high voltage electricity, in order to prevent the high voltage electricity from leaking to cause harm to operators, the main body 10 is made of an insulating material. Preferably, the insulating material is an epoxy resin. The epoxy resin has on the one hand good insulating properties and on the other hand a low density, so that the body 10 is light and easy to handle.
A connector 20 is provided at the first end 12 of the body 10. The connecting member 20 may be, for example, a male connector, one end of which is fixed to the first end 12 of the main body 10 and can be rotated by the main body 10, and the outer wall of the other end of which is provided with an external thread 25. The attachment member 20 is connected to a mounting and dismounting device 30 by a screw thread 25. Preferably, the dismounting device 30 is provided as a hexagonal dismounting head. Therefore, as long as the hexagonal dismounting head with the same size as the fastening screw of the central switch cabinet contact is selected, the main body 10 can be rotated to drive the connecting piece 20 to rotate, and further drive the hexagonal dismounting head to rotate. Thereby, the fastening screw is loosened or tightened by rotating the hexagonal socket head in a forward or reverse direction. Moreover, the dismounting device 30 is connected with the connecting piece 20 through a thread 25, and can be freely installed and replaced, so that dismounting devices 30 with different sizes or different forms can be freely replaced according to actual needs, and the application range of the dismounting device 30 is enlarged. Therefore, the contact replacer 100 for the central switch cabinet can complete the dismounting operation of the contact and can be used for dismounting other live devices and accessories thereof.
In a preferred embodiment, the length of the body 10 is set to 80-100 cm. The body 10 of this size satisfies the principle of lightness satisfactorily. Tests show that in the length range, the main body 10 not only can effectively bear the high voltage of more than 40KV and is higher than the voltage of the high voltage electricity carried on the contact of the central switch cabinet, but also meets the working requirement of the safe distance of equipment with points of 35KV and below.
As shown in fig. 1, the second end 14 of the body 10 is configured to be coupled to a female head 18. A booster lever 40 with a handle 45 is attached to the second end 14 of the body 10. The force application rod 40 is formed in a substantially T-shape, and is screw-coupled to the body 10 to be freely installed or removed. The stress application rod 40 is used for providing enough torque for the main body 10, so that workers can conveniently install or detach the middle-mounted switch cabinet contact in a labor-saving manner. Preferably, the length of the handle 45 is set to 10cm to 30cm, which is made of a telescopic rod, and the length can be freely adjusted within this range. In this way, it is convenient to provide the appropriate torque by adjusting the length of the handle 45. Also, the female connection 18 may be used to connect other components. For example, when the length of the main body 10 does not satisfy the requirement, a connecting member such as an extension bar may be connected through the female connecting head 18.
In a preferred embodiment, a grip 15 is further sleeved on the main body 10 near the second end 14 of the main body, and the outer wall of the grip 15 has uneven lines. When the worker needs to disassemble and assemble the middle-mounted switch cabinet contact, the worker needs to rotate the stressing rod 40 by one hand and hold the grip 15 by the other hand, so that the main body 10 is righted and rotated in an auxiliary manner. In this state, the grip 15 can provide sufficient friction force to facilitate the work.
The use of the contact replacer 100 for a central-type switchgear according to the utility model is briefly described below.
When the contacts of the central switch cabinet need to be disassembled, firstly, a proper disassembling device 30 is selected according to the size of the contacts, and the selected disassembling device 30 is connected to the connecting piece 20 through the threads 25. The lever 40 is then mounted on the second end 14 of the body and the length of the handle 45 is adjusted. Finally, the dismounting device 30 is aligned with the fastening screw of the contact on the central switch cabinet, and the contact is dismounted from the central switch cabinet by rotating the main body 10 through the stress application rod 40.
When the maintenance work is finished, the contact can be installed again. At this time, the body 10 is rotated reversely, so that the fastening screw is tightened to fix the contact to the mid-type switch cabinet again. Finally, the force applying rod 40 and the dismounting device 30 at the two ends of the main body 10 are sequentially dismounted.
Finally, it should be noted that the above-mentioned embodiments are only preferred embodiments of the present invention, and do not limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing examples, or that equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
