Example Embodiment

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0031] The invention provides a battery charging circuit to solve the problem of high cost in the prior art.

[0032] Specific, such as figure 2 As shown, the battery charging circuit 100 is applied to the auxiliary equipment test device 200 in the main line electric locomotive and is connected to the socket 300 in the library and the main contactor of the auxiliary equipment test device 200 in the library. The battery charging circuit 100 includes: a first circuit breaker Q1 and power conversion unit; among them:

[0033] The input end of the first circuit breaker Q1 is connected to the socket 300 in the library, and the output end is connected to the input end of the power conversion module;

[0034] The two output ends ...

Abstract

The invention provides a storage battery charging circuit and a warehouse-in auxiliary machine test device. During over discharge of a storage battery, the alternating current of a warehouse-in socket is received by a power supply conversion module through a first closed circuit breaker, and the alternating current is converted into a direct current output to the coil of a main contactor, so that the main contact of the main contactor is closed after the coil of the main contactor is electrified, and then the alternating current of the warehouse-in socket flows through the main contact of the main contactor and charges a storage battery through a storage battery charger of the warehouse-in auxiliary machine test device; a general 3AC380V power supply in the industrial field can be received through the warehouse-in socket, and a special warehouse-in charging socket does not need individually to receive electric energy of special ground charging equipment, so that the problem that the cost is high in the prior art is avoided.

Description

technical field [0001] The invention relates to the technical field of mainline electric locomotives, in particular to a storage battery charging circuit and a testing device for auxiliary machines in a warehouse. Background technique [0002] In the rail transit industry, main line electric locomotives use control batteries as backup control power and starting power. When the output voltage of the control battery is within the voltage range specified by the standard, the control system of the locomotive can start normally and realize the control of bow raising, so that the locomotive can obtain electric energy from the catenary. [0003] A typical existing auxiliary machine test and battery charging circuit in the locomotive garage, such as figure 1 shown. When the locomotive normally takes current from the catenary, the on-board battery charger 103 will use the three-phase AC of the locomotive (such as figure 1 shown) or the single-phase AC auxiliary power supply is tra...
