10kV power distribution cabinet isolation baffle opening tool

Abstract

The invention belongs to the field of electric power auxiliary tools, and particularly relates to a 10kV power distribution cabinet isolation baffle opening tool using a lever principle. The 10kV power distribution cabinet isolation baffle opening tool comprises a lever body and is characterized in that one end of the lever body is provided with a ratchet bin, the other end of the lever body is provided with an unlocking pressure plate, the lever body at one side of a ratchet is internally provided with a pawl and a spring, the head part of the pawl is contacted with the ratchet, the tail part of the pawl is connected with one end of the spring, the other end of the spring is pressed against the internal part of the lever body, the tail part of the pawl is provided with a pull wire, the other end of the pull wire is connected with the unlocking pressure plate, a rotating shaft of the ratchet is externally connected to a first connecting shaft, the other end of the first connecting shaft is provided with a pull rod, the other end of the pull rod is provided with a first ferrule, and the external part of the lever body is provided with a second ferrule. The 10kV power distribution cabinet isolation baffle opening tool is ingenious in structure and convenient to use, and the lever body can be manufactured to meet safety requirements in length very easily. In addition, the 10kV power distribution cabinet isolation baffle opening tool is small in size, has fastening and locking functions, and does not occupy too much space inside the cabinet, thereby being convenient for the staff to work in the cabinet.

Description

technical field [0001] The invention belongs to the field of electric power auxiliary tools, in particular to an opening tool for an isolation baffle of a 10-kilovolt power distribution cabinet using the principle of leverage. Background technique [0002] The isolation baffle is required to open the isolation baffle for the static contacts in the 10 kV power distribution cabinet for phase verification, withstand voltage test, and electrical inspection. The isolation baffle is driven by the isolation baffle mechanism in the switch cabinet, so the 10 kV power distribution cabinet The internal isolation baffle mechanism (also known as the valve mechanism) is opened. One opening method is that the skilled operator fixes the front end of the valve mechanism lever with a clip or a rope, and two people need to cooperate with each other at the same time to complete the opening and closing of the isolation baffle. The traditional method is that it is difficult to ensure a sufficient...

[0002] The isolation baffle is required to open the isolation baffle for the static contacts in the 10 kV power distribution cabinet for phase verification, withstand voltage test, and electrical inspection. The isolation baffle is driven by the isolation baffle mechanism in the switch cabinet, so the 10 kV power distribution cabinet The internal isolation baffle mechanism (also known as the valve mechanism) is opened. One opening method is that the skilled operator fixes the front end of the valve mechanism lever with a clip or a rope, and two people need to cooperate with each other at the same time to complete the opening and closing of the isolation baffle. The traditional method is that it is difficult to ensure a sufficient safety distance between the operator and the charged body (10kv safety distance is 0.35 meters) and the opening quality cannot be guaranteed. The isolation baffle may be closed suddenly when the staff is working, which will bring danger to the staff.

[0003] In addition, some opening devices are used to open the isolation baffle after the trolley base in the switch is modified, but the structure of these modified trolley bases is large, which hinders the construction operation of the staff entering the cabinet, and its reliability is not stable
