Abstract
The invention provides a high voltage discharge tube. The discharge tube comprises insulating tubes, connection loops, conducting rods and electrodes, wherein the connection loops are respectively connected at the two ends of the insulating tubes and are used for sealing the insulating tubes; one end of the conducting rods is fixedly arranged at the inner sides of the connection loops; the electrodes are fixed at the other end of the conducting rods; binding posts for connecting the discharge tube to a circuit are arranged at the outer sides of the connection loops; and the insulating tubes are filled with pure hydrogen for extinguishing arc. The discharge tube has the following advantages: the discharge tube has small volume, bears high overvoltage, prevents explosion, protects the environment and does not have polarity (the polarity is not obvious), residual voltage or noises; the overvoltage energy rapidly breaks down and is discharged in the discharge tube and is earthed to be released via the discharge tube, so the discharge tube is suitable for the inflammable and explosive hostile environment; the sealed discharge tube ensures the discharge voltage to be stable and not to be affected by the humidity and air pressure of the ambient environment; and the discharge tube has low capacitance and inductance, thus not affecting the protected circuit.

Background technology
High-voltage discharge tube is a kind of novel electrovacuum low-carbon environment-friendly product, and it is two electrode quick high-pressure electronic switching tubes.Be mainly used in vacuum switch (vacuum circuit-breaker and vacuum contactor) switching overvoltage and atmospheric over voltage protection.Protection high-tension motor, power transformer, power capacitor etc. exempt from over-voltage breakdown and damage.
Under normal circumstances, when overvoltage was lower than the discharge tube place value, discharge tube two electrodes were in off-state, have very high insulation property between electrode.When overvoltage is higher than the discharge tube place value, (counts microsecond) fast between discharge tube two electrodes and puncture, and pass through big pulse current with very low internal resistance.The pulse current peak size is decided by the energy storage and the instantaneous peak energy of lightning wave of external circuit.Absorb overvoltage with discharge tube, when overvoltage acted on discharge tube, the discharge tube conducting so superpotential peak energy passes through the release of discharge tube ground connection fast, thereby had protected High-Voltage Electrical Appliances and equipment to exempt from damage reliably.After the overvoltage crest passed through, electric current descended immediately, insulation property (number microsecond) recovery again fast between two electrodes in the discharge tube, and discharge tube two electrodes are in original off-state again.
High-voltage discharge tube of the prior art: can generate heat during work, not be suitable for vacuum switch switching overvoltage and atmospheric over voltage protection; The discharge back easily produces electric arc, leaves residual voltage, is not suitable for using in inflammable and explosive adverse circumstances; Non-sealing fully, the guiding discharge spread of voltage is subject to the humidity and the effects of air pressure of external environment; Self-healing property is poor, just can not continue after the use repeatedly to use, and needs repair and replacement, uses inconvenient.
Summary of the invention
The invention provides a kind of high-voltage discharge tube of easy to use and safety and stability.
For addressing the above problem, scheme of the present invention is: a kind of high-voltage discharge tube, it comprises insulated tube, be fixedly connected on described insulated tube two ends respectively is used for the clamping ring of insulated tube sealing, is positioned at conducting rod that the clamping ring of described insulated tube and an end and respective side is fixedly connected, is fixed on electrode on each described conducting rod other end, is arranged on and is used for outside the described clamping ring discharge tube is connected to binding post on the circuit, is filled with the pure hydrogen that is used for arc extinguishing in the described insulated tube.
Optimize, also be provided with the getter that is used to absorb other gases except that hydrogen purity in the described insulated tube, make discharge tube have arc quenching effect preferably with hydrogen in the assurance discharge tube.
Further, described getter is a pick aluminium getter, and is arranged between the conducting rod and clamping ring of the arbitrary end of insulated tube.
Further, described clamping ring, conducting rod and binding post all adopt oxygen-free copper to make.
Optimize, described insulated tube employing insulation property 95 porcelain are preferably made.
Because discharge tube is wanted multiple discharge, repeated use, described electrode adopts the anti-tungsten-molybdenum alloy of fulgerizing to make.
For making discharge voltage moderate, described distance between electrodes is 1.9～2.1 times of insulated tube inner diameter.
For arriving good sealing effectiveness, described clamping ring solid welding is at the insulated tube two ends.
Further, described conducting rod and the coaxial setting of insulated tube.
The present invention compared with prior art has following advantage: volume is little, bears the overvoltage height, and is explosion-proof, environmental protection; Discharge tube does not generate heat during work, is specially adapted to vacuum switch switching overvoltage and atmospheric over voltage protection; Nonpolarity (polarity is not obvious), no residual voltage, no noise, the disruptive discharge in discharge tube fast of overvoltage energy discharges by discharge tube ground connection, is applicable to inflammable and explosive rugged environment; The discharge tube of sealing makes discharge voltage stable, is not subjected to the humidity and the effects of air pressure of external environment; Discharge tube selfcapacity and inductance are all very little, and protected circuit is not influenced; Good self-healing property is arranged, can be repeatedly used, and the velocity of discharge is fast, resume speed is fast, and is easy to use, and the life-span is long.
