Problems solved by technology

However, due to the limitation of the structure of each operating mechanism, the remote opening mechanism can only be arranged on the upper end of the operating mechanism or other specific positions, which is obviously not conducive to the modular design of the product, and with the change of market demand, sometimes the use of The latter will require a second shunt coil, but the existing single-opening semi-axis method cannot meet this demand

Embodiment Construction

[0023] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0024] see Figure 1 to Figure 4 , the existing circuit breaker body 1 including the operating mechanism constitutes the main body of the entire circuit breaker. The operating mechanism body 2 for installing the opening rotating shaft is installed on the circuit breaker body 1, which includes a basic opening mechanism, which can be a common opening mechanism body of an existing circuit breaker. A circuit breaker remote opening mechanism provided by the present invention further includes an accessory module 6, a first opening rotating shaft 9 arranged on the operating mechanism body 2, a second opening rotating shaft arranged on the operating mechanism body 2 7 and tie rod 4. The accessory module 6 receives the remote opening electric control signal. The second opening rotary shaft 7 is connected to the accessory module 6 .

Abstract

According to a remote opening mechanism of a circuit breaker provided by the invention, one shaft is added or an original shaft is divided into a first opening rotating shaft and a second opening rotating shaft, and the first opening rotating shaft and the second opening rotating shaft are connected with each other through a pull rod, so that the first opening rotating shaft and the second opening rotating shaft are linked with the opening half shaft of an operating mechanism. Therefore, an original operation opening half shaft (the first opening rotating shaft) and a newly added shaft (the second opening rotating shaft) can enable the operating mechanism to act so as to realize the opening function, so that a part of original accessories can be transferred to the newly added shaft, and the positions of the original accessories can be reserved; and a second accessory is added at the newly added shaft, so that the technical problem that parts are difficult to arrange under the condition of considering the size of the circuit breaker due to many and complex circuit breaker mechanisms is well solved.

Description

technical field [0001] The invention relates to circuit breaker equipment, in particular to a circuit breaker opening mechanism. Background technique [0002] At present, the operating mechanism of most circuit breakers has a remote opening function, which is generally powered through the shunt release, and the shunt release works to hit the opening half shaft on the operating mechanism body of the circuit breaker. However, due to the limitation of the structure of each operating mechanism, the remote opening mechanism can only be arranged on the upper end of the operating mechanism or other specific positions, which is obviously not conducive to the modular design of the product, and with the change of market demand, sometimes the use of The latter will require a second shunt coil, but the existing single-opening semi-axis method cannot meet this demand. Contents of the invention [0003] The invention provides a remote opening mechanism of a circuit breaker, which is pr...
