Abstract
The present invention relates to a kind of high-voltage breaker explosion chamber pressure measurement method based on built-in trachea, comprise the following steps: an elastic trachea is installed in high-voltage breaker explosion chamber, at elastic tracheal strips preliminary filling quantitative gas, indoor magnetic block is fixed on the top of elastic trachea；High-voltage breaker explosion chamber outer wall is installed an outdoor magnet buoy；When in high-voltage breaker explosion chamber, pressure changes, then air tubing length changes therewith, and the position of indoor magnetic block changes the most therewith, drives the position of the outer magnet buoy of arc-chutes to change, thus realizes measuring the function of arc extinguishing room pressure.The present invention is reasonable in design, the change of outdoor magnet buoy position is driven by the change of air tubing length, thus reach to measure in real time the purpose of arc extinguishing room pressure change, efficiently solve and cannot measure the problem of pressure in high-voltage breaker explosion chamber in real time, there is the features such as easy to use, stable and reliable for performance.
Description
Technical field
The invention belongs to primary cut-out technical field, a kind of high-voltage breaker explosion chamber pressure measurement method based on built-in trachea.
Background technology
Primary cut-out is equipment conventional in high-tension circuit.The arc-chutes of primary cut-out are total enclosing structure, and arc-chutes 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 arc suppression chamber pressure is measured, but, owing to arc-chutes are full-closed structures, there is no effective technological means at present and the pressure of arc-chutes is measured in real time.
Summary of the invention
It is an object of the invention to overcome the deficiencies in the prior art, it is provided that a kind of reasonable in design, quick and precisely, high-voltage breaker explosion chamber pressure measurement method based on built-in trachea easy to use.
The present invention solves existing technical problem is that and takes techniques below scheme to realize:
A kind of high-voltage breaker explosion chamber pressure measurement method based on built-in trachea, comprises the following steps:
Step 1, installing an elastic trachea in high-voltage breaker explosion chamber, this elasticity trachea is close on the inwall of high-voltage breaker explosion chamber, at elastic tracheal strips preliminary filling quantitative gas, indoor magnetic block is fixed on the top of elasticity trachea；
Step 2, an outdoor magnet buoy is installed with indoor magnetic block opposite position on high-voltage breaker explosion chamber outer wall；
Step 3, when in high-voltage breaker explosion chamber, pressure changes, then air tubing length changes therewith, and the position of indoor magnetic block changes the most therewith, drives the position of the outer magnet buoy of arc-chutes to change, thus realizes measuring the function of arc extinguishing room pressure.
And, the arc-chutes outer wall that outdoor magnet buoy moves up and down is provided with the scale of pressure in reaction high-voltage breaker explosion chamber, is shown the pressure of high-voltage breaker explosion chamber by this scale intuitively.
Advantages of the present invention and good effect be:
The present invention is by placing the trachea of preliminary filling quantitative gas and being fixedly mounted with indoor magnetic block at trachea top in arc-chutes, simultaneously, arc-chutes outer wall arranges the outdoor magnet buoy corresponding with indoor magnetic block, the change of outdoor magnet buoy position is driven by the change of air tubing length, thus reach to measure in real time the purpose of arc extinguishing room pressure change, efficiently solve and cannot measure the problem of pressure in high-voltage breaker explosion chamber in real time, the feature such as there is quick and precisely, easy to use, reliable and stable.
Accompanying drawing explanation
Fig. 1 is the measuring principle schematic diagram of the present invention.
Detailed description of the invention
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 built-in trachea, uses high-voltage breaker explosion chamber pressure gauge as shown in Figure 1 that the high-voltage breaker explosion chamber pressure of total enclosing structure is measured survey in real time.This measurement apparatus includes trachea 3, indoor magnetic block 2 and outdoor magnet buoy 5, described trachea uses elastomeric material to make, in this trachea is arranged on high-voltage breaker explosion chamber 1 and it is close together with arc-chutes inwall, at tracheal strips preliminary filling quantitative gas 4, described indoor magnetic block is fixed on the top of trachea, and described outdoor magnet buoy is arranged on arc-chutes outer wall and on the position corresponding with indoor magnetic block.The arc-chutes outer wall that outdoor magnet buoy moves up and down is provided with the scale of pressure in reaction high-voltage breaker explosion chamber, more can demonstrate force value in high-voltage breaker explosion chamber intuitively.
The high-voltage breaker explosion chamber pressure measurement method of the present invention comprises the following steps:
Step 1, installing an elastic trachea in high-voltage breaker explosion chamber, this elasticity trachea is close on the inwall of high-voltage breaker explosion chamber, at elastic tracheal strips preliminary filling quantitative gas, indoor magnetic block is fixed on the top of elasticity trachea.
Step 2, an outdoor magnet buoy is installed with indoor magnetic block opposite position on high-voltage breaker explosion chamber outer wall, and the scale of pressure in reaction high-voltage breaker explosion chamber is set on the arc-chutes outer wall that outdoor magnet buoy moves up and down.
Indoor magnetic block and outdoor magnet buoy are adjacent in high-voltage breaker explosion chamber inner side and outer side by magnetic respectively, when indoor magnetic block position is moved, outdoor magnet buoy can be driven to do synchronizing moving by the effect of magnetic.
The arc-chutes outer wall that outdoor magnet buoy moves up and down arranges the scale of pressure in reaction high-voltage breaker explosion chamber, force value in high-voltage breaker explosion chamber can be demonstrated intuitively.
Step 3, when in high-voltage breaker explosion chamber, pressure changes, then air tubing length changes therewith, and the position of indoor magnetic block changes the most therewith, drives the position of the outer magnet buoy of arc-chutes to change, thus realizes measuring the function of arc extinguishing room pressure.
When arc extinguishing room pressure raises, compression gas pipe, trachea shortens, and drives indoor magnetic block and outdoor magnet buoy to move down；When arc extinguishing room pressure declines, trachea expands elongated, drives indoor magnetic block and outdoor magnet buoy to move up, and by the scale being shaped with on arc-chutes outer wall, obtains the pressure of force value in high-voltage breaker explosion chamber.
It is emphasized that; embodiment of the present invention is illustrative; rather than it is determinate; therefore the present invention includes the embodiment being not limited to described in detailed description of the invention; every other embodiments drawn according to technical scheme by those skilled in the art, also belong to the scope of protection of the invention.
