[0002] With the continuous development of social economy, smart grid has been put on the development agenda by the country. As an important part of the power distribution network, the small circuit breakers used for terminal power distribution are also gradually developing in the direction of intelligence. At present, there are two types of intelligent small circuit breakers: one is to add 1P to place the control circuit board and power device; the other is to place the control circuit board in a small space such as the gap of the single-pole short circuit breaker.
[0003] These two methods have the following problems: one is that the product is large in size and cannot be replaced 1:1 with the traditional circuit breaker; the production and assembly process is complicated and cannot be assembled automatically; the wiring is complicated and it is inconvenient for employees to assemble manually; especially for multi-pole products with zero-sequence mutual inductors, one pole must be assembled before the second pole can be assembled, which has a certain impact on the stability of the mechanism. Utility Model Content
[0004] The purpose of the utility model is to provide a modularly assembled intelligent miniature circuit breaker to solve the existing problems raised in the above background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a modularly assembled intelligent miniature circuit breaker, comprising a mechanism module and a sampling control module;
[0006] The small circuit breaker is provided with an operating mechanism, a closing drive unit and an opening drive unit in a mechanism module; and a sampling control circuit board is provided in the sampling control module.
[0007] Preferably, a sampling component is provided on the left side of the mechanism module, and the electrical output end of the sampling component is electrically connected to the electrical output end of the sampling control circuit board.
[0008] Preferably, the mechanism module is independently assembled, and is provided with mounting slot one, mounting slot two, mounting slot three, mounting slot four, mounting slot five, and mounting slot six on the outside.
[0009] Preferably, the sampling control module is provided with a base and an upper cover.
[0010] Preferably, the base is provided with mounting buckle one, mounting buckle two, and mounting buckle three, and the base is provided with mounting buckle four, mounting buckle five, and mounting buckle six.
[0011] Compared with the prior art, the beneficial effects of the utility model are:
[0012] 1. By setting up independent mechanism modules and sampling control modules, modular assembly of small circuit breakers is realized. Each module is configured separately according to market demand, which better meets the diverse needs of the market and improves product production turnover efficiency;
[0013] 2. Through the independent assembly mechanism, the influence of the assembly of the sampling control part on the core components of the operating mechanism can be avoided, thereby further improving the qualified rate of the finished product and greatly reducing the complexity of the assembly process.
