Universal sensor mounting structure and circuit breaker action characteristic analyzer thereof

Technical Field

The utility model relates to the technical field of circuit breakers, in particular to a general sensor mounting structure and a circuit breaker action characteristic analyzer thereof.

Background

The high-voltage vacuum circuit breaker is generally named because the arc extinguishing medium and the insulating medium of the contact gap after arc extinguishing are both high vacuum; the arc extinguishing device has the advantages of small volume, light weight, suitability for frequent operation and no maintenance in arc extinguishing, and is more popular in power distribution networks.

Because the inside of the vacuum chamber is provided with an arc extinguishing chamber, the inside is vacuum, when the movable contact and the static contact are separated under the action of the operating mechanism, electric arcs are generated between the contacts, steam volatilizes from the surface of the contacts at high temperature, the electric arcs are extinguished when the electric arcs pass through the vacuum chamber naturally, and the medium strength between the contacts is restored rapidly.

Because of the use of the moving contact, the inside of the arc-extinguishing chamber has the possibility of certain vacuum leakage, so that arc extinction is not timely enough, the risk of explosion of the circuit breaker is easy to occur, based on the risk, the moving characteristic tester of the circuit breaker is required to detect various mechanical characteristics of the circuit breaker, and plays an important role in a power system, and the moving characteristic tester of the circuit breaker is key equipment for ensuring the safe operation of the power system. The method can detect the action and disconnection characteristics of the circuit breaker, so as to eliminate faults in the power grid, discover potential hidden dangers in time, ensure safe and reliable operation of the power grid, detect the circuit breaker by adopting a sensor mode, for example, detect the action stroke of a switch by adopting a linear motion sensor, detect the speed of the switch by adopting a universal sensor, the sensors are all sensors which are used in the circuit breaker detection test, when the sensors are used, in order to keep the combination with the circuit breakers of different types, the sensors are installed by using a universal bracket, but in the installation process, for example, the universal sensor is directly fastened and installed on a lifting rod or a horizontal connecting rod of the switch, or other transmission rods, the socket direction of the universal sensor is required to be consistent with the movement direction of the movable rod, the universal sensor is kept parallel with the movable rod as much as possible, if the installation is skewed, and meanwhile, the sensors cannot shake, when the switch acts, the sensors are required to bear the movement of the movable rod together, and cannot shake the movable rod, otherwise, the sensor cannot accurately test data.

Referring to fig. 1 and 2, the conventional universal bracket has a higher degree of freedom and less constraint, so that after the universal sensor is installed, the universal sensor is easily connected with the movable rod to generate a position deviation, and a higher error occurs in an experimental result.
