Ministry of Electronics Industry of the People's Republic of China Standard RX-54 Microwave Gas Discharge Tube
SJ2244--82
This standard applies to RX--54 microwave gas discharge tube (hereinafter referred to as switch tube), which is a 10-centimeter band broadband receiving protection switch tube, used in radar equipment of 72.14mm×34.04mm waveguide system. This standard is a supplement to the general technical conditions for microwave gas discharge tubes (SJ343-73) (hereinafter referred to as "general technical conditions"). Except for the contents specified in this standard, the rest shall be implemented in accordance with the relevant provisions of the general technical conditions. Dimensions
The dimensions of the switch tube shall comply with the provisions of Figure 1. 2 Parameter specification
The parameters of the switch tube shall comply with the provisions of the parameter specification table. Glass and metal sealing test
Take 10 switch tubes (it is allowed to take tubes with some unqualified items of the same process, but the ignition current must be qualified) for a single glass and metal sealing test. First, use 5 tubes for the test. After the test, all the switch tubes are qualified, and the test is qualified. The other 5 tubes are not tested. If 1 of the 5 tubes is unqualified, another 5 tubes are required to be tested. After the test, all the switch tubes are qualified, and the test is qualified. If 2 (or more) of the 5 switch tubes tested first are unqualified, or 1 (or more) of the 5 tubes tested later are unqualified, the test is unqualified. Retest is required according to the general technical regulations.
When all the switch tubes are qualified in the first quarter (or three consecutive months) test, the test will not be carried out again in this year. Otherwise, it will be carried out according to the general technical regulations.
Shock test
The acceleration is 5g, the impact frequency is 50-70 times/min, and the impact is 500 times in the horizontal and vertical directions. 5 Low temperature test under working condition
Under the condition of ambient temperature of -55±2℃, maintain for 30 minutes, then add ignition voltage and high power to measure the amplitude recovery time.
6 Working condition High temperature test
Under the condition of ambient temperature of 70±2℃, maintain for 30 minutes, then add ignition voltage and high power to measure the wave tip energy.
7 Amplitude recovery time
7.1 The amplitude recovery time is calculated based on the attenuation of the receiving signal by the switch tube as 3dB. 7.2 The frequency of the detection signal is the center frequency of the tube being tested. Issued by the Ministry of Electronics Industry of the People's Republic of China on December 22, 1982 and implemented on July 1, 1983
Tube cap firmness test
SJ2244—82
After the moisture mixing test, the switch tube that has been left to stand for two hours is placed on special equipment, and the torque of the pipe cap is gradually increased to 0.017kg·m to check the firmness of the pipe cap. The pipe cap should not be loose after the test. 9 Relaxation oscillation
When the ignition current is greater than 30μA, no harmful relaxation oscillation with an amplitude reaching the zero line should be observed on the oscilloscope. See Figure 2.
10 When the output of the switching tube is less than 100 per quarter (or for three consecutive months), its routine test shall be carried out once every six months (or for six consecutive months). The test shall be carried out in accordance with Articles 17, 18, 19 of the General Technology (SJ34373) and Article 3 of this standard.
11 When the output of the switching tube is less than 100 per quarter (or for three consecutive months), its life test shall be carried out once every six months (or for six consecutive months). The test shall be carried out in accordance with Articles 22 and 23 of the General Technology (SJ343-73). 12 Life test
12.1 Take 5 switching tubes Conduct life test. 12.2 During the life test, the standard life parameters are tested at 150, 225, 250, 263, 270 and 300 hours respectively.
12.3 See the Appendix (Supplement) for the principle diagram of the life test. 13 Weight
The weight of the switch tube is inspected once a year.
14 After the packaging drop tube and transportation bump test, the ignition current and voltage standing wave coefficient of the switch tube should comply with the provisions of the parameter specification table.
15 When using the switch tube, a soft metal gasket should be added to its connection surface to ensure good electrical contact. 16 When the average power of the switch tube reaches 500W or more, strong air cooling should be used. 17 Article 5, paragraph (2) of the General Technology (SJ34373) is not applicable to this standard. 2
