Embodiment Construction

[0042] The above and other technical features and advantages of the present invention will be described in more detail below in conjunction with the accompanying drawings.

[0043] see figure 2 As shown, it is a structural and functional block diagram of the circuit breaker for preventing disconnection of the present invention; the circuit breaker for preventing disconnection includes: a circuit breaker body 20, which is arranged on the power line to realize the communication of the power line 10. The external control line 11 is connected to the circuit breaker, and the external control line 11 realizes the external control processing of the circuit breaker. The external control line 11 has a voltage signal, and a circuit breaker includes an anti-break Line control unit; it includes: a power line voltage detection subunit 21, used to obtain the voltage signal on the power line 10, and detect whether there is a voltage signal on the power line 10; an external control line volt...

Abstract

The invention provides a breaker for preventing wire break, comprising a breaker body which is arranged on a power line and has external control wire access. The breaker is characterized by comprising a wire break prevention controlling unit, a power line voltage detecting sub-unit for detecting whether the power line has voltage signals or not, an external control wire voltage detecting sub-unit for detecting whether the external control wire has voltage signals or not, and a breaking action execution sub-unit for leading the breaker body to generate breaking actions when one of the power line and the external control wire does not have voltage signals.

Description

technical field [0001] The invention relates to a circuit breaker, in particular to a circuit breaker with the function of preventing abnormal disconnection of a power line and an external control line combined with the circuit breaker, which can be applied in a prepaid electricity management system. Background technique [0002] For the power sector, the switch breaker is an essential device to ensure the safety of electricity consumption and to switch lines. It can be applied to high-voltage or low-voltage conditions, and can be set on single-phase power lines or three-phase On the power line, we refer to the existing circuit breaker as the circuit breaker body here, which at least has the function of breaking the circuit and receiving the external control signal through the external control line. [0003] see figure 1 As shown, it is a schematic diagram of the internal structure of the existing circuit breaker; here, it is set on a single-phase power line as an example, ...
