Detailed Description
The following provides a preferred embodiment of the present invention with reference to the accompanying drawings to explain the technical solutions of the present invention in detail.
Fig. 1-1 is a schematic diagram of an overall structure of a vacuum circuit breaker. Fig. 1-2 is a left side view of fig. 1-1. Fig. 2-1 is a schematic view of a structure of a frame and chassis combination on a vacuum circuit breaker. Fig. 2-2 is a schematic view of a frame structure on a vacuum circuit breaker. Fig. 2-3 are schematic structural views of the chassis truck. As shown in the above figures, in the structure of the circuit breaker, the dimensions (front-rear dimension, right-left dimension) of the chassis 2 and the vacuum circuit breaker frame 1 are very important. If there is a deviation in the dimensions, there is a great risk of the operating conditions of the circuit breaker in the switchgear cabinet.
Factors causing deviation in mounting dimensions: the mounting hole that the frame corresponds is screw 6, but the chassis car has the condition that a model corresponds multiple model circuit breaker, and consequently there are a plurality of mounting holes in the chassis car at present, and the mounting hole is long waist hole 5, consequently can't pinpoint when chassis car and frame amalgamation installation, and then lead to the deviation to appear in mounting dimension.
