Disconnecting link anti-mistaken-touch locking assembly for electrical equipment

Abstract

The invention relates to the technical field of power equipment, and discloses a disconnecting link anti-mistaken-touch locking assembly for electrical equipment; the assembly comprises a disconnecting link rod, one end of the disconnecting link rod is fixedly connected with a sliding groove, the inner side wall of the sliding groove is slidably connected with a sliding block, and the outer side wall of the sliding groove is slidably connected with a sliding column. And one end of the sliding column is fixedly connected with a reset spring. When the disconnecting link rod needs to be overturned, only the sliding block needs to be pressed, the sliding block slides towards the interior of the sliding groove, the sliding block drives the sliding column to ascend, a toothed plate on the sliding column drives a gear to rotate, the gear drives a transmission rod to rotate, and finally the convex face of a cam on the transmission rod makes contact with a first baffle; a locking pawl is driven to rotate, so that locking pawl does not lock a ratchet wheel; a rotating seat on the disconnecting link rod can rotate, and the disconnecting link rod can be turned over; and the disconnecting link anti-mistaken-touch locking assembly can effectively avoid the phenomena that animals interfere with the knife switch rod and mistakenly touch the disconnecting link rod.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to a knife switch anti-mistouch locking assembly for electric equipment. Background technique [0002] Power equipment mainly includes power generation equipment and power supply equipment. Power generation equipment is mainly power plant boilers, steam turbines, gas turbines, water turbines, generators, transformers, etc. Power supply equipment is mainly transmission lines of various voltage levels, transformers, contactors, etc. Among them, in the power supply equipment, in order to control the opening and closing of the circuit, a knife switch will be installed to control the circuit. [0003] In the prior art, since the knife switch is usually at a higher position, there will be a large number of birds and other animals staying on the knife switch lever at a higher position. When the weight of the animal is heavy, the supporting force of the knife switch lever is less...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a knife switch anti-mistouch locking assembly for electric equipment, which is equipped with a ratchet and a pawl to lock the rotation axis of the knife switch lever to prevent birds and other animals from accidentally touching The advantages of the knife lever solve the problem that because the knife is usually at a higher position, there will be a large number of birds and other animals staying on the knife lever. When the weight of the animal is heavy, the weight of the knife lever will If the supporting force is less than the gravity of the animal, the knife switch lever will automatically turn over, causing the circuit to be automatically opened or disconnected, which will affect the normal operation of the electrical equipment and cause large economic losses.
