Description
Technical field
The present invention relates to a kind of method solving pole vacuum detecting and structure, particularly a kind of solution pole
The method of online vacuum detecting and structure.
Background technology
Pole is a kind of apg forming technology of utilization epoxy resin by vacuum interrupter and upper and lower wire outlet seat and connection
All encapsulating pours into pole to part, and defines insulation crust after epoxy resin cure, makes whole chopper every phase pole
Post becomes the part of an entirety.The advantage of pole, one is modularized design, and structure is simple, and detachable part is few, reliable
Property high；Two is high insulating bar ability.Surface insulation is become volume insulation by it, compares air insulation, decreases environment
Impact, substantially increases dielectric strength.Meanwhile, it can make chopper size reduction, is conducive to switch cubicle miniaturization.
Pole, during dispatching from the factory or using, needs the vacuum indoor to vacuum extinction to be detected and monitor,
Ensure the reliability of product quality and use, and now pole cannot be carried out with vacuum degree measurement at present, and conventional magnetron is true
Empty detection can only detect the vacuum interrupter not having sealing, and be now to solution is that vacuum interrupter is encapsulated as after pole
Also vacuum can be detected.But, due to the particularity of pole structure, (upper and lower ends of cylindrical pole set respectively
Have a wire outlet seat perpendicular to pole), coil cannot be set up by such structure, if put with very big coil
Go, then the vacuum that cannot detect vacuum or mistake is detected, therefore, can only first detect the vacuum of vacuum interrupter with
Afterwards, then by vacuum interrupter carry out sealing, product caused to be difficult to when secondary damage discover so during sealing,
Come into the market and can cause brand prestige, meanwhile, vacuum that cannot be indoor to arc extinguishing in using running is monitored, at present
Using by the way of have plenty of in vacuum extinction interior installation vacuum detector, and by the transmission means such as wirelessly, vacuum is transmitted
To outside receiving device, this structure one is that manufacturing cost is high, and two is that vacuum detector is located inside arc-chutes, easily damages
Bad, it is difficult to overhaul, meanwhile, it is poor to be wirelessly transferred effect, monitoring is inaccurately.
Content of the invention
It is an object of the invention to, a kind of method solving the online vacuum detecting of pole and structure are provided.The present invention
Have easy to detect, product quality is secure, low cost of manufacture, it is hardly damaged, easily overhauls, data transfer effect is good, monitoring essence
True feature.
Technical scheme: a kind of method of the online vacuum detecting of solution pole, is by pole
Hull outside arranges vacuum detecting line bag, and wraps connection coil power supply lead wire head in vacuum detecting line, and testing equipment is connected
The vacuum in pole can be detected according to magnetic control discharge method after on coil power lead riser.
A kind of structure realizing aforesaid solution pole online vacuum detecting method, pole is originally provided with very in vivo
Empty arc-chutes and vacuum detecting line bag, vacuum detecting line is wrapped and is connected with coil power lead riser.
The aforesaid structure solving the online vacuum detecting of pole, is provided with the vacuum interrupter in described pole
Static contact and moving contact, static contact and moving contact are connected with the upper wire outlet seat on pole body and lower wire outlet seat respectively
Connect, between upper wire outlet seat and lower wire outlet seat, described static contact and moving contact are located at vacuum detecting to described vacuum detecting line bag
The center of line bag.
The aforesaid structure solving the online vacuum detecting of pole, described vacuum detecting line bag is passed through with vacuum interrupter
Epoxy resin apg pours into a mould sealing simultaneously, and, in the cylinder of pole body, the two ends of described coil power lead riser are stretched out admittedly
Envelope shell.
The aforesaid structure solving the online vacuum detecting of pole, described vacuum detecting line bag is copper coil.
Beneficial effects of the present invention:
1st, the present invention passes through to arrange vacuum detecting line bag outside pole, and wraps connection coil power supply lead wire head online, by
In vacuum detecting line bag, sealing is integral on pole simultaneously, therefore, can carry out secondary after pole makes and finishes again
Vacuum detecting, and in use, vacuum that can be indoor to vacuum extinction in real time be detected it is achieved that online
Detection purpose, only testing equipment need to be connected on coil power lead riser during detection, easy to detect, simultaneously it is ensured that
The quality of pole, maintains brand prestige；In addition, with respect to the vacuum detector being wirelessly transferred, the vacuum inspection of the present invention
Survey line bag manufacturing cost is lower, is hardly damaged, and service life is longer, meanwhile, easily facilitates maintenance；Furthermore, the present invention is to pass through
Wired connection mode carries out data transmission, and more preferably, vacuum monitoring is more accurate for laser propagation effect.
2nd, the present invention passes through vacuum detecting line bag sealing, in the cylinder of pole body, to improve vacuum detecting line
The steadiness of bag, meanwhile, profile is more attractive in appearance.
