Abstract
The 12kV vacuum arc extinguish chamber with the vacuum degree and temperature online detection function structurally comprises a high-voltage part, the vacuum arc extinguish chamber, a contact, a shielding case and an electric field probe; three electric field probes with completely same temperature characteristics and electric field sensitivity are respectively arranged near a shielding case of the vacuum switch three-phase vacuum arc-extinguishing chamber, and three electric field signals and an environment temperature signal are simultaneously input into a computer, so that the online detection of the contact temperature and the vacuum degree in the vacuum arc-extinguishing chamber is realized. The utility model discloses vacuum interrupter with vacuum, temperature on-line measuring can realize the on-line measuring of vacuum in vacuum interrupter on-line measuring of contact temperature and the vacuum interrupter simultaneously, has overcome the defect of two kinds of indirect detections of coupling capacitance and photoelectric conversion.
Description
Technical field
The utility model relates to power transmission and distribution circuit breaker design manufacturing technology field, press equipment for power transmission and distribution in being applied to, have the novel evacuated arc control device of 12kV of vacuum degree, temperature online detection.
Background technology
Along with vacuum switch is used in the mesolow field more and more at large, the vacuum degree of vacuum interrupter becomes the emphasis that the user is concerned about.Because only under certain vacuum degree, the reliability of vacuum switch just can be guaranteed.The test of vacuum level of vacuum arc-quenching chamber has different requirement with occasion difference of living in.From big aspect, can be divided into two big types of offline inspection and online detections.The method of offline inspection has a lot, and develop also comparative maturity.Online detection will be monitored the variation of its vacuum degree at any time under the prerequisite of not changing switch main body structure and running status.At present, also can't realize the direct measurement of vacuum degree both at home and abroad, two kinds of indirect methods that are used for the online detection of vacuum degree are coupling capacitance method and electro-optical conversion method.The coupling capacitance method puts forward according to the measurement of partial discharge principle.If the compressive resistance between charged contact to the intershield cover of tested vacuum interrupter descends owing to vacuum degree reduces; Then when power-frequency voltage rises to a certain value from zero point; Equivalent capacitance between charged contact and the radome discharges, and this local discharge signal can carry out on-line monitoring through two partial discharge probes between radome and ground connection case shell.
The online detection of breaker temperature at present is primarily aimed at the temperature variations of circuit breaker connector and bus overlapped points, does not also relate to the device and the technology that can detect the vacuum arc-extinguishing chamber contact temperature.
The utility model content
The purpose of the utility model provides the vacuum interrupter that a kind of 12kV has vacuum degree, temperature online detection.
This 12kV has the vacuum interrupter of vacuum degree, temperature online detection; Its structure is formed and is comprised high-pressure section, vacuum interrupter, contact, radome electric field probe; Adopt temperature characterisitic and duplicate three electric field probes of electric field sensitivity; Be installed in respectively near the radome of vacuum switch three-phase vacuum interrupter, and three road electric field signals and ambient temperature signal are imported computer simultaneously, realize the detection of the indoor contact temperature of vacuum extinction; Be employed in and insert a high-voltage capacitance C2 in the insulated support of electric field probe; The withstand voltage height of this electric capacity, capacitance is very little of electric field probe provides a measuring basis, solves three-phase vacuum interrupter external electrical field skewness and influences measurement sensitivity.
Adopt the beneficial effect of present technique scheme: vacuum interrupter with vacuum, temperature online detection; Can realize the online detection of online detection of the indoor contact temperature of vacuum extinction and the indoor vacuum degree of vacuum extinction simultaneously, overcome the defective of coupling capacitance and two kinds of indirect detection of light-to-current inversion.
