Abstract
The invention relates to a method for measuring the pressure in an arc extinguish chamber of a high-voltage circuit breaker based on the hydraulic technique. The method comprises the following steps: installing a hydraulic pipe in the arc extinguish chamber of the high-voltage circuit breaker, wherein the hydraulic pipe is closely attached on the inner wall of the extinguish chamber of the high-voltage circuit breaker, the hydraulic pipe is internally filled with a fixed quantity of liquid, and an indoor magnetic floating block is placed on the top surface of the liquid; an outdoor magnetic buoy is arranged on the outer wall of the arc extinguish chamber of the high-voltage circuit breaker and at the place corresponding to the indoor magnetic floating block; when the pressure in the arc extinguish chamber of the high-voltage circuit breaker changes, the volume of the fixed quantity of liquid in the hydraulic pipe changes correspondingly; and the position of the indoor magnetic floating block in the hydraulic pipe and the position of the outdoor magnetic buoy change, and the function of monitoring the pressure in the arc extinguish chamber in real time is realized. The method is reasonably designed; the purpose of monitoring the pressure change in the arc extinguish chamber in real time is realized; the problem that the pressure in the arc extinguish chamber of the high-voltage circuit breaker cannot be monitored in real time is effectively solved; and the method has the advantages of being convenient to use, stable and reliable in performance and the like.
Description
Technical field
The invention belongs to primary cut-out technical field, especially a kind of high-voltage breaker explosion chamber pressure measurement method based on hydraulic technique.
Background technology
Primary cut-out is equipment conventional in high-tension circuit.The arc control device of primary cut-out are totally-enclosed structure, and arc control device must keep certain pressure, its arc extinguishing ability of guarantee.In the running of primary cut-out, in order to ensure the arc extinction performance of primary cut-out, need to monitor arc suppression chamber pressure, still, because arc control device are full-closed structures, there is no at present effective technological means the pressure of arc control device is carried out to Real-Time Monitoring.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of reasonable in design, high-voltage breaker explosion chamber pressure measurement method based on hydraulic technique is fast and accurately provided.
The present invention solves existing technical problem and takes following technical scheme to realize:
A high-voltage breaker explosion chamber pressure measurement method based on hydraulic technique, comprises the following steps:

Brief description of the drawings
Fig. 1 is measuring principle schematic diagram of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the embodiment of the present invention is further described.
A kind of high-voltage breaker explosion chamber pressure measurement method based on hydraulic technique, adopt pressure measxurement as shown in Figure 1 to carry out Real-Time Monitoring to the high-voltage breaker explosion chamber pressure of totally-enclosed structure, this measurement mechanism comprises hydraulic tube 2, indoor magnetic floating block 3 and outdoor magnet buoy 4, hydraulic tube is arranged in high-voltage breaker explosion chamber 1 and is close together with arc control device inwall, in hydraulic tube, put into quantitative liquid 5, described indoor magnetic floating block is placed on the top of quantitative liquid in hydraulic tube, described outdoor magnet buoy is arranged on arc control device outer wall and on the position corresponding with indoor magnetic floating block.The scale that is provided with reaction high-voltage breaker explosion chamber internal pressure on the arc control device outer wall moving up and down at outdoor magnet buoy, demonstrates high-voltage breaker explosion chamber internal pressure value more intuitively.
High-voltage breaker explosion chamber pressure measurement method of the present invention comprises the following steps:
Step 1, a hydraulic tube is installed in high-voltage breaker explosion chamber, this hydraulic tube is close on the inwall of high-voltage breaker explosion chamber, puts into quantitative liquid in hydraulic tube, magnetic floating block in the holding chamber of the top of liquid.
Step 2, on high-voltage breaker explosion chamber outer wall and with indoor magnetic floating block opposite position, one outdoor magnet buoy is installed, and on the arc control device outer wall moving up and down at outdoor magnet buoy, is provided with the scale of reaction high-voltage breaker explosion chamber internal pressure.
Indoor magnetic floating block and outdoor magnet buoy are adjacent to respectively in high-voltage breaker explosion chamber inner side and outside by magnetic, in the time that indoor magnetic floating block position is moved, can drive outdoor magnet buoy to do synchronizing moving by the effect of magnetic.
The scale that is provided with reaction high-voltage breaker explosion chamber internal pressure on the arc control device outer wall moving up and down at outdoor magnet buoy, can demonstrate high-voltage breaker explosion chamber internal pressure value intuitively.
Step 3, in the time that high-voltage breaker explosion chamber internal pressure changes, the quantitative liquid volume in hydraulic tube changes thereupon, indoor magnetic floating block position in hydraulic tube also changes thereupon, thereby drive the correspondence position of outdoor magnet buoy to change, realize the function of Real-Time Monitoring arc suppression chamber pressure.
In the time that arc control device internal pressure raises, the liquid in hydraulic tube is compressed, and liquid level step-down drives indoor magnetic floating block and outdoor magnet buoy to move down; In the time that arc control device internal pressure declines, the expansion of liquids in hydraulic tube, liquid level rises, and drives indoor magnetic floating block and outdoor magnet buoy to move up.
It is emphasized that; embodiment of the present invention is illustrative; instead of determinate; therefore the present invention includes and be not limited to the embodiment described in embodiment; every other execution modes that drawn by those skilled in the art's technical scheme according to the present invention, belong to the scope of protection of the invention equally.
