Signaling devices universal automatic UAS-1
Signaling devices universal automatic UAS-I are intended for warning by light and sound signals of the personnel servicing mobile mechanisms with the portable boom equipment about approach of parts of the mechanism on dangerous distance to wires of transmission lines (power transmission line) of alternating current e from 220 V to 750 kV.
The note, Without clicking the range selector button, at power supply inclusion, the device is ready to work near the power transmission line 220/380 B‚ sensitivity of the device maximum).
1.3. Depending on a device location mode on the mechanism (a constructive and electric binding of the device to the mechanism), and also its completeness (the number of the antennas which are included in the package of the device, lengths, cable connections, etc.) the following modifications of the UAS-1 device of the Tab., 1 are developed).
2.1. Distance from an arrow of the mechanism on which signaling DANGEROUSLY, to the closest wire of lines works
electricity transmissions from 220 V to 750 kV makes GOST 12.1.013.78 ESBT which was not less set by requirements. Construction. Electrical safety. General requirements, namely:
- at a voltage from 0,22 kV to 1 kV - Z m;
- at a voltage from 1 kV to 20 kV - 4 m;
- at a voltage from 35 kV to 110 kV - 8 m;
- at a voltage from 150 kV to 220 kV of-10 m;
- at a voltage from 330 kV to 750 kV - 18 m;
2.2. The device is supplied with automatic check of working capacity in general, including check of integrity of antenna cables and the scheme with delivery of a signal is OPERATIONAL. Frequency of following of a signal of operability from 0,5 to 2 Hz. At fault of any node of the device or violation of integrity of a chain of antenna assembly continuous light and sound signals of danger are given.
2.3. Power supply of the device is carried out from a vehicle network of the mechanism by tension as 12 V and 24 V with fluctuations of rated value from 10,8B (21,6B) to 15B (3O of V).
2.4. The current consumed by a product does not exceed Z A.
2.5. On climatic and mechanical operating conditions the product corresponds to the GOST 3940-84 Electric equipment autotractor. The general specifications with execution option "At" in are saved by working capacity after influences:
- ambient temperatures from minus-40 to plus 55 ° C
- relative humidity of 95% at a temperature - 40 ° C
- vibration loads with a frequency of 50 Hz with acceleration of 50 m / с2
- percussions, loadings about acceleration of 100 m / с2.
2.6. the allowed current through the contacts provided for connection of external signaling in actuation mechanisms makes 5 A at a voltage up to 30B.
