Handcart HD4Z-40.16.25

Full range of models are as follows: withdrawable HD4 / Z-40.12.25 withdrawable HD4 / Z-40.12.31 withdrawable HD4 / Z-40.16.25 withdrawable HD4 / Z-40.16.31 withdrawable HD4 / Z-40.20.25 withdrawable HD4 / Z-40.20.31 withdrawable HD4 / Z-40.25.25 withdrawable HD4 / Z-40.25.31 withdrawable HD4 / Z-40.31.25 withdrawable HD4 / Z-40.31.31 Notes: 1, HD4 sulfur hexafluoride circuit breaker is a mature technology ABB Group learn the advantages of widely used high-pressure sulfur hexafluoride circuit breaker self-energy (thermal expansion + pressure air-assisted blowing), is the ABB Group share Experience crystal technology. It has excellent breaking performance, breaking characteristic smooth, over-voltage is very low. Inflatable interrupter pole completely sealed, maintenance-free period. 2, HD4 sulfur hexafluoride circuit breakers can be used for three-phase AC 40.5kv distribution system to control and protect lines, transformers, motors, cables and capacitors, etc. As a result of sulfur hexafluoride from carve-off technology, HD4 circuit breaker operation does not produce over-voltage, it is particularly suitable for grid capacity increase, the transformation of motors, cables and other insulating very weak case. 3, HD4 sulfur hexafluoride circuit breakers and VD4 vacuum circuit breakers in size completely interchangeable. 4, withdrawable HD4, electric operating mechanism includes the following standard accessories: auxiliary contact switch 12 (Q / 1 ... Q / 12, in which the four normally open, normally closed contact 5 for external use), energy storage Pressure switch status position switch (BS1, BS2), beginning of the second trolley position BT1 and BT2, sub-gate release MC, MO, charging motor MS, latching solenoid RL1, with a two-stage operation level control loop (SF6 low gas pressure - alarm and SF6 gas pressure is insufficient - lockout); mechanical energy storage status indicators, mechanical sub-gate button, mechanical sub-gate status indicator, operation counter, secondary circuit air plug to prevent different types of hand car swap locking devices: Used advancing mechanism handcart grounding device, the shutter drive mechanism, a circuit contact arm and plum contacts.
