Embodiment Construction
[0010] Embodiments of the present invention are described in further detail below in conjunction with the accompanying drawings:
[0011] A device for measuring the pressure of the arc extinguishing chamber of a high-voltage circuit breaker based on a built-in elastic ball, such as figure 1 As shown, it includes an elastic ball 3, an indoor magnetic block 2 and an outdoor magnetic buoy 5. The elastic ball is made of elastic material. In chamber 1, a certain amount of gas is pre-filled in the elastic ball, the indoor magnetic block is fixed on the top of the elastic ball, and the outdoor magnetic buoy is installed on the outer wall of the arc extinguishing chamber at a position corresponding to the indoor magnetic block. On the outer wall of the arc extinguishing chamber where the outdoor magnetic buoy moves up and down, there is a scale reflecting the pressure in the arc extinguishing chamber of the high voltage circuit breaker, which can more intuitively display the pressure ...

The invention relates to a device for measuring pressure in a high-voltage circuit breaker arc extinguish chamber based on a built-in elastic ball. The device is technically characterized by comprising the elastic ball, an indoor magnetic block and an outdoor magnetic floating mark; the elastic ball is made of elastic materials and installed in the high-voltage circuit breaker arc extinguish chamber through movable sliding blocks at the side end and the bottom end, the elastic ball is inflated with quantitative gas in advance, the indoor magnetic block is fixed to the top end of the elastic ball, and an outdoor magnetic floating mark is installed in the position, corresponding to the indoor magnetic block, of the outer wall of the arc extinguish chamber. The device is reasonable in design, the elastic ball is installed in the arc extinguish chamber through the movable sliding blocks, the indoor magnetic block is fixedly arranged on the top of the elastic ball, and the position of the outdoor magnetic floating mark is driven to change through the change of the size of the elastic ball, so that the change of the pressure in the arc extinguish chamber is measured in real time, and the problem that the pressure in the high-voltage circuit breaker arc extinguish chamber cannot be measured in real time is effectively solved; the device has the advantages of being simple in structure, convenient to use, stable, reliable and the like.
Description
technical field [0001] The invention belongs to the technical field of high-voltage circuit breakers, in particular to a pressure measuring device for an arc extinguishing chamber of a high-voltage circuit breaker based on a built-in elastic ball. Background technique [0002] High voltage circuit breakers are commonly used equipment in high voltage circuits. The arc extinguishing chamber of the high-voltage circuit breaker is a fully enclosed structure, and the arc extinguishing chamber must maintain a certain pressure to ensure its arc extinguishing ability. During the operation of the high-voltage circuit breaker, in order to ensure the arc-extinguishing performance of the high-voltage circuit breaker, it is necessary to measure the pressure of the arc-extinguishing chamber. real-time pressure measurement. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, and provide a pressure measuring device fo...
