Abstract

The invention discloses a control circuit for a power generator for a hazardous article transport vehicle. The control circuit comprises a power generator, a storage battery connected with the outer part of the power generator and a vehicle electrical appliance load; the power generator comprises an adjustor, a magnet exciting coil and a three-phase rectifier bridge, wherein the output end of the three-phase rectifier bridge is connected with the storage battery and the vehicle electrical appliance load; the input end of the three-phase rectifier bridge is simultaneously connected with the anode of a rectifying diode set and a star-shaped stator coil; the negative electrode of the magnet exciting coil is connected with the adjustor; the other end of the adjustor is connected with a ground wire; the positive electrode of the magnet exciting coil is connected with a piece of dropping equipment; the other end of the dropping equipment is connected with a power master switch by a charging indicator lamp; the dropping equipment comprises a relay and a first external joint; the cathode of the rectifying diode set and the regulator are connected with the first external joint. The control circuit can avoid generating overvoltage and over-current, and is also applicable to the power generator on the hazardous article transport vehicle. Moreover, the control circuit is low in production cost, and is easy to maintain and change.

Description

technical field [0001] The invention relates to a control circuit of a generator, in particular to a control circuit of a generator for a dangerous goods transport vehicle, which is mainly suitable for preventing the generator from generating overvoltage and overcurrent. Background technique [0002] For vehicles engaged in the road transport of dangerous goods, clear regulations have been issued at home and abroad, such as: "ADR-2009 EU Agreement on International Road Transport of Dangerous Goods", "R105-1998 Unified Requirements for Structural Certification of Dangerous Goods Transport Vehicles", "GB20300 –2006 Safety Technical Conditions for Vehicles Transporting Explosives and Highly Toxic Chemicals by Road” and “GB21668-2008 Structural Requirements for Vehicles Transporting Dangerous Goods”, both of which put forward certain requirements for the electrical system of vehicles engaged in road transport of dangerous goods, such as : The cab shall be provided with a control...
