Description

Technical Field

[0001] The utility model relates to the technical field of reclosing circuit breakers, and particularly relates to a reclosing circuit breaker with a reduced volume. Background Technique

[0002] A reclosing circuit breaker is an electrical device that plays an important role in the power system. When a fault occurs in the power line and causes an excessive current, the circuit breaker will quickly trip to cut off the circuit and protect the line and equipment from damage. The reclosing function will automatically control the circuit breaker to close again within a certain period of time after the circuit breaker trips. If the fault is transient, such as a short-term short circuit caused by lightning, the line can resume normal power supply after reclosing; however, if the fault is permanent, such as serious damage to the line, the circuit breaker will trip again after reclosing to avoid causing greater impact on the system.

[0003] Currently, the power supply board inside the existing reclosing circuit breaker is usually installed at the bottom of the base, and an installation position is reserved at the bottom of the base. However, this installation method results in a relatively large height dimension of the base of the reclosing circuit breaker, and further leads to a relatively large overall volume of the reclosing circuit breaker, occupying a relatively large space during installation and use. Content of the Utility Model

[0004] The utility model aims to provide a reclosing circuit breaker with a reduced volume to solve the problems raised in the above background technique.

[0005] To achieve the above object, the utility model provides the following technical solutions:

[0006] A reclosing circuit breaker with a reduced volume includes a reclosing circuit breaker body and a circuit board. The reclosing circuit breaker body includes a base, a middle seat, and a top cover. The middle seat is installed on the top of the base, and the top cover is installed on the top of the middle seat. An installation cavity is provided inside the middle seat, and a circuit board installation slot is provided on one side of the installation cavity. The circuit board is installed in the circuit board installation slot.

[0007] Preferably, a control board is provided in the accommodation slot, and a control panel is provided on the top of the control board.

[0008] Beneficial Effects

[0009] One or more of the above technical solutions in a reclosing circuit breaker with a reduced volume provided by an embodiment of the utility model have at least one of the following technical effects:

[0010] The utility model is provided with a circuit board mounting groove on one side inside the middle seat of the reclosing circuit breaker body, and the position structure of the components inside the middle seat is reasonably arranged and optimized, so that the circuit board can be mounted inside the middle seat, avoiding an increase in height dimensions, without reserving a mounting position at the bottom of the base, reducing the height dimension of the base, thereby reducing the height of the reclosing circuit breaker body, occupying less space during installation, and improving the space utilization rate.
