The regulations are based on the actual use of the technical requirements. This procedure was first formulated. Comprehensive calibration device verification procedures railroad track signal test equipmentScopeThe order applies to the first railway track signal integrated test equipment calibration device (hereinafter referred to as integrated calibration device) Second test, verification and subsequent use of checks. 2 Overview Comprehensive calibration device is mainly used in railway track signal line test equipment test and calibration. Its main functions are. Single-frequency output signal frequency, voltage and current; frequency shift signal (including the center frequency of 550Hz, 650Hz, 750Hz, 850Hz frequency shift of the signal, ZPW-2000, UM71, WG-21A, etc.) frequency, voltage, Stream; 25Hz, 50Hz voltage phase sensitive track signal phase; voltage ac counting track signals, time intervals, etc. Standard signal, standard compensation capacitor and impedance. 3 metering performance requirements 3.1 single-frequency output 3.1.1 Frequency Output ranges from 5Hz ~ 3kHz, the maximum permissible error shall not exceed ± 0.03Hz. 3.1.2 Voltage (5 ~ 25) Hz frequency band output range (0.1 ~ 10) V, 25Hz ~ 3kHz band output range (0.1 ~ 400) V, the maximum permissible error shall not exceed ± 0.5%. 3.1.3 Current 5Hz ~ 3kHz band output range (50 ~ 500) mA, the maximum permissible error shall not exceed ± 0.5%, By induction coil output current range of 50mA ~ 20A. 3.2 Frequency Shift Output 3.2.1 frequency shift (center frequency of 550Hz, 650Hz, 750Hz, 850Hz frequency shift signal) 3.2.1.1 upper and lower frequencies. output range (460 ~ 940) Hz, the maximum permissible error shall not exceed ± 0.03Hz. 3.2.1.2 The low frequency range. low frequency modulation frequency output range (6 ~ 30) Hz, shall not exceed the maximum permissible error ± 0.003Hz. 3.2.1.3 Voltage. shift in frequencies, the output range (0.1 ~ 400) V, shall not exceed the maximum permissible error ± 0.5%. 3.2.1.4 Current. shift frequencies, the output range (50 ~ 500) mA, shall not exceed the maximum permissible error ± 0.5%, by the induction coil output current range of 50mA ~ 20A. 3.2.2 ZPW-2000, UM71, WG-21A 3.2.2.1 upper and lower frequencies. output range (1.6 ~ 2.7) kHz, shall not exceed the maximum permissible error ± 0.03Hz. ...... |
