China HV Switchgear Tester Brief introduction This Vacuum circuit breaker analyzer adopts a new type of excitation coil to test the vacuum of the arcing chamber by means of magnetron discharge method, without disassembly of the arcing chamber.Synchronous control and data acquisition are carried out by microcomputer, so that the sensitivity of field test of vacuum degree of arc extinguishing chamber reaches 10-5pa. The most prominent feature is the use new excitation coil and data processing method to achieve the vacuum degree measurement without disassembly. The instrument has the advantages of convenient use, simple operation, non-disassembly measurement and high test accuracy. It鈥檚 widely used in electric power, steel, petrochemical, textile, coal, railway,etc. Hot tags: circuit breaker analyzer,Circuit Breaker Test Equipment,circuit breaker test set Technical data 1.Tested object锛歏arious vacuum switch tubes. 2.Test method锛欰 new type of excitation coil is used to measure vacuum tube without disassembly. 3.Application锛欼t鈥檚 one machine multipurpose type, can measure many kinds of vacuum open magnetism. 4.Test range锛?0-5鈥?0-1 Pa 5.Accuracy锛?0-5鈥?0-4 Pa, 15% 10-4鈥?0-3 Pa, 15% 10-3鈥?0-2 Pa, 10% 10-2鈥?0-1 Pa, 10% 6.Magnetic field voltage: 1700V 7.High voltage of pulse electric field 锛?0KV 8.Open distance of switch tube in vacuum test: normal open distance 9.Working environment: -20鈩儈40鈩?/p 10.Weight: 12kg 11.Size: 420脳320脳280 (mm) Testing principles of instrument Pull and open two contacts pole of interrupter arc chamber for certain distance, applied high pulse voltage, placed interrupter arc chamber within spiral coil, or placed new electromagnetic coils outside the interrupter arc chamber, it will generate high voltage sync pulse magnetic field in the interrupter arc chamber. Under the influence of this strong electric field and pulsed magnetic field, the electrons in the interrupter arc chamber will move spirally, collide with residual gas and produce ionization, and between the ion current and the density of residual gas(the vacuum value)it is proportional. For different types of vacuum tubes (tube type), because of its different structure the value of ion current is not same under the condition of same contacts open distance, same vacuum, same electric and magnetic fields. By some experiments, the corresponding relationship curve between different type tube鈥檚 vacuum value and ion electrical source can be calibrated. As the ion current is detected, the vacuum value of this vacuum tube type can be obtained by the curve of ion current and vacuum. More related products F.A.Q 1.
