Embodiment 1

[0039] refer to figure 2 , a train circuit breaker with a semiconductor chip includes: a circuit breaker body and a compact control module installed on the circuit breaker body, wherein the circuit breaker body is the original mechanical structure part of the circuit breaker, so it will not be repeated; it can be understood that this The circuit breaker main body in the embodiment at least includes a tripping mechanism and is an electromagnetic system, so as to ensure the implementation basis of the compact control module. The main body of the compact control module is integrated into a small box fixed on the outer wall of the circuit breaker for installation. The compact control module includes:

[0040] Sampling unit 1, which is connected to the voltage sensor and the current sensor in the high-voltage box, and is used for outputting a rated signal when the voltage and current detection values ​​meet rated conditions; wherein, the rated conditions include a low-voltage clo...

Embodiment 2

[0064] The difference from Embodiment 1 is that the controller is also connected with an over-phase safety module.

[0065] It can be understood that the alternating current is three-phase; when the train is connected to the pantograph, the instantaneous power consumption is single-phase, so the railway uses electricity in sections, and each section uses one phase; when the train goes from one phase area to another phase area It needs to go through a phase separation zone. The over-phase safety module in this embodiment is used to prevent electrical damage caused by the train not being disconnected in time when the over-phase is over.

[0066] The over-phase safety module includes: an over-phase logic unit and a train position acquisition unit; wherein, the over-phase logic unit can be another processing chip and its supporting peripheral circuit, which is connected to the controller and the train position acquisition unit, and is used for When the train is out of phase, the ...

Abstract

The invention discloses a train circuit breaker with a semiconductor chip and a control method thereof. The circuit breaker comprises a circuit breaker body, a compact control module is installed on the circuit breaker body, and the compact control module comprises: a sampling unit, which is connected to The voltage sensor and current sensor in the high-voltage box are used to output the rated signal when the voltage and current detection values ​​meet the rated conditions; the rated conditions include the low-voltage switch-on hold threshold and the current overload trigger threshold; the controller is connected to the sampling The output terminal of the unit is used to respond to the rated signal and is used to manage the closing and holding sequence of the circuit breaker body; the closing and opening holding execution unit is connected to the controller to drive the circuit breaker when the voltage and current detection values ​​meet the rated conditions The device body remains closed or open. The present application has the effect of improving the convenience of application of the circuit breaker.

Description

technical field [0001] The present application relates to the technical field of train electrical safety protection, in particular to a train circuit breaker with a semiconductor chip and a control method thereof. Background technique [0002] For rail vehicles and DC vehicles, it is necessary to ensure that their high-voltage DC circuits are protected from overcurrent, short-circuit, surge current and unsafe catenary voltage, and to protect the personal safety of maintenance technicians. [0003] refer to figure 1 In order to achieve the above purpose, the high-voltage integrated system of the train is correspondingly integrated with contactors, voltage sensors, grounding switches, lightning arresters, DC circuit breakers, and current sensors. In order to achieve "plug and play", the above components are integrated into a high-voltage box. [0004] Regarding the above circuit breaker, the inventor believes that its overall mechanical structure requires more hardware coope...
