TECHNICAL FIELD
[0001] The present application relates to the technical field of special equipment for assembling or repairing switch devices, and particularly to a GIS circuit breaker arc extinguishing chamber assembling and detecting device. BACKGROUND
[0002] The gas insulated metal enclosed switchgear (GIS) refers to a metal enclosed switchgear that uses SF6 or other insulating gas as an insulating medium. The circuit breaker GIS core element is one of the components, and the assembly process requires high precision. The previous assembly method is to place the GIS circuit breaker arc extinguishing chamber on a platform, and manually turn it over and gradually assemble it. However, the circuit breaker arc extinguishing chamber needs to be turned over 4 times, and it is time-consuming and laborious to turn it over due to the heavy weight of the circuit breaker arc extinguishing chamber. In addition, the assembly precision cannot be guaranteed. The arc extinguishing chamber guide shaft parts need to be assembled after the arc extinguishing chamber is aligned and assembled by pulling the static end pull rod. The maximum single-phase split and close force of the arc extinguishing chamber is 900N, which cannot be achieved by manual operation. Moreover, for ZF12D-126 GIS circuit breakers, due to the compact structure and small phase spacing, it is difficult to tighten the M8x25 internal hexagonal cylinder head screw of the insulating cylinder, which affects the assembly efficiency. In addition, after the assembly of the circuit breaker arc extinguishing chamber is completed, further detection is often required to determine whether the arc extinguishing chamber split and close torque is normal, so as to avoid rework due to unqualified products. The assembly and detection processes are carried out step by step, which greatly reduces the production efficiency and increases the production cost. SUMMARY

The two rotating connecting ears 11 are arranged opposite each other to rotate and assemble the tilting seat 3. A control button 12 is fixedly installed on the outer side of the right front side of the support platform. A tilting motor 13 and a tilting reducer 14 are fixedly installed on the outer side of the right front side of the support platform at the positions corresponding to the rotating connecting ears 11.

The arc-extinguishing chamber is opened and closed according to the set parameters, and the opening and closing force values of the arc-extinguishing chamber are measured to see if they are qualified; after measuring one phase, the opening and closing tension and pressure values of the other two phase arc-extinguishing chambers are measured, and finally the measurement is completed; after the measurement is completed, if the performance of the three-phase arc-extinguishing chamber meets the technical requirements, the remaining auxiliary parts are assembled, the arc-extinguishing chamber is adjusted to a vertical state, and the three-phase arc-extinguishing chamber is hoisted as a whole for subsequent assembly.
