Description

Technical Field

[0001] This utility model relates to the technical field of temperature measuring ring replacement devices, specifically a live replacement device for temperature measuring rings in a handcart cabinet. Background Technology

[0002] The temperature measuring ring of the switchgear is installed on the stationary contact side of the switchgear. When replacing the temperature measuring ring using the traditional method, due to the lack of live-line working tools, all incoming and outgoing lines of the busbar must be de-energized before personnel can pull out the handcart-type circuit breaker, open the contact locking baffle of the switchgear, and remove and replace it by hand or by making a metal hook. The traditional method adopts a "five-step" operation, and the operation process is as follows: ① power outage and switching operation → ② setting up safety measures → ③ temperature measuring ring replacement → ④ acceptance and restoration measures → ⑤ power restoration and switching operation. Once the busbar is de-energized, it will cause a large-scale power outage, affecting the reliability of power supply and causing load loss. Therefore, it is not easy to shut down the power for maintenance. As a result, after the temperature measuring ring is damaged, it is often impossible to replace it in time while energized. At this time, the contact temperature of the switchgear will be unmonitored, and the temperature rise cannot be detected in time, putting the switchgear at risk of burning out.

[0003] Therefore, this utility model provides a live replacement device for the temperature measuring ring of the handcart cabinet to solve the above problems. Utility Model Content

The structure is designed so that the grooves on the first insulating bracket 33 and the second insulating bracket 34 provide insulating support for the clamping component 4. The clamping component 4 is then used to inspect and replace the temperature measuring ring inside the cabinet. The insulating clamping and fixing of the clamping component 4 enables the replacement of the temperature measuring ring while it is energized, improving the timeliness of the replacement and minimizing losses. The chassis 1 adopts a hand-cranked structure, and all the components above are connected to the displacement end of the chassis 1.
