Embodiment Construction
[0009] The test device of the network control cabinet, including a connector, each channel of the connector is connected to the regulated power supply through a circuit breaker; the negative channel of the two output channel pairs of the connector is respectively connected to one end of an indicator light , and the other ends of all indicator lights are grounded. Each channel of the connector is connected to each circuit breaker through a terminal block, and the indicator light is drawn from the terminal block. During specific implementation, there are three connectors, respectively DB9, DB15, and DB25, to be compatible with the interface of the Indian electric locomotive network control cabinet; the number of the circuit breakers is the same as the number of channels of the connector DB25 with the largest number of channels, that is, the circuit breaker The number of circuit breakers and indicator lights is 25, and the channels of the other two connectors DB9 and DB15 share c...

The invention provides a testing device for a network control cabinet. The device is used for testing the quality or faults of the network control cabinet. The problems that an existing testing deviceof the network control cabinet is complex in structure and tedious in test operation are solved. The testing device of the network control cabinet comprises a connector, wherein each channel of the connector is connected with a voltage-stabilizing power supply through a circuit breaker; negative channels of output channel pairs of the connector are connected with one ends of indicating lamps respectively, every two output channel pairs form a group, and the other ends of all the indicating lamps are grounded. According to the testing device, testing of input and output functions of the network control cabinet is achieved, the structure of the testing device is simplified, the operation is easy, and the efficiency of routine testing of the network control cabinet is improved. The testing device is particularly suitable for testing the network control cabinet of an electric locomotive exported to India, and is also suitable for testing other network control cabinets.
Description
technical field [0001] The invention is a testing device of a network control cabinet, which is used for testing the quality or failure of the network control cabinet. Background technique [0002] The traditional network control cabinet test tooling needs to simulate the input and output signals with the help of a hardware-in-the-loop simulation platform. The test device is complex and the test operation is cumbersome, which is not suitable for the routine test requirements of mass production. Traditional network control cabinets use F48 connectors, while the external connectors of network control cabinets for electric locomotives exported to India use DB9, DB15, and DB25 connectors, which are significantly different from domestic products of the same type. Contents of the invention [0003] The present invention solves the problems of complex structure and cumbersome test operation of the existing network control cabinet testing device, and provides a network control cab...
