Problems solved by technology

Although the modular structure design can have high flexibility and can be applied to a variety of power distribution systems, in the prior art, the combination of two independent modules is used for setting, and for some small spaces, circuit breakers need to be installed , due to the volume problem, it is impossible to add another automatic reclosing structure separately, so that the circuit breaker cannot be reclosed automatically

Embodiment 1

[0060] This embodiment discloses an MCB structure, which can protect the access circuit and avoid damage to electrical equipment when a short circuit or other abnormal current occurs in the access circuit. The miniature circuit breaker is a common protection device in the current electrical system. It can trip in time to form an open circuit when a short circuit or other overvoltage fault occurs in the circuit, thereby protecting the safety of the load equipment. However, because many electronic equipment or communication equipment are installed in remote areas or where it is difficult for maintenance personnel to reach as soon as possible, once the miniature circuit breaker in the power distribution module operates and loses power, if it cannot be reset and powered on for a long time, it will not only affect the system normal operation of the device, it may cause problems with other associated devices.

Embodiment 2

[0073] This embodiment discloses a circuit breaker, the main structure of which includes a housing 1 and functional components arranged in the housing 1 . Such as Figure 1-9As shown, it can be seen that the housing 1 is a cuboid structure, the height of the front is less than 45mm, which is 1U in the size standard, and the width is less than 18mm. The reason for its smaller overall size is to adopt a smaller powertrain inside, and at the same time to reorganize its interior in a targeted manner, so as to increase the internal compactness.

[0074] Such as Figure 4 As shown, an opening is provided on the upper part of the housing, and from the opening from top to bottom are the automatic reclosing component, the tripping component, the arc extinguishing structure 12, the control component and the connection port. The connection port includes an input end and an output end for connecting to an external circuit, and both the input end and the output end adopt a rectangular me...

Abstract

The invention discloses an internet-of-thing miniature circuit breaker with a reclosing function. The internet-of-thing miniature circuit breaker comprises a tripping assembly and an automatic reclosing assembly, which are arranged in the same housing and are in linkage. The tripping assembly is connected with an input end and an output end which are connected into the circuit breaker. The automatic reclosing assembly comprises an internet-of-things module capable of communicating with a far end; and the internet-of-thing module transmits the on-off state of the tripping assembly to the far end for feedback, and the internet-of-thing module receives a far end control signal and controls reclosing of the tripping assembly through the automatic reclosing assembly. The automatic reclosing assembly with the automatic reclosing function is integrated in the same housing and can be matched with a linkage mechanism, control is conducted through the control assembly with the remote communication function, and disconnection and reclosing are achieved.

Description

technical field [0001] The invention belongs to the technical field of electrical equipment, and in particular relates to an Internet of Things miniature circuit breaker with a reclosing function. Background technique [0002] A circuit breaker is a switching device that can close, carry and break current under normal circuit conditions and can close, carry and break current under abnormal circuit conditions within a specified time. Circuit breakers are divided into high-voltage circuit breakers and low-voltage circuit breakers according to their scope of use. The division of high and low voltage boundaries is relatively vague. Generally, those above 3kV are called high-voltage electrical appliances. Circuit breakers can be used to distribute electric energy, protect power lines and motors, etc., and can automatically cut off the circuit when they have serious overload, short circuit and undervoltage faults, and their functions are equivalent to those of fuse switches and ov...
