Circuit breaker crucial effect is played in safety, the stable operation of electrical network, and circuit breaker intelligent controller is the core component of circuit breaker as the infrastructure device of power distribution protection, its work reliable and stable most important concerning circuit breaker.The site environment of actual motion is often very abominable for circuit breaker; usually can be subjected to for example interference of wireless electromagnetic such as mobile phone, intercom radiation; therefore be defined among the industry standard GB14048.2-2008 that circuit breaker must be working properly under the situation that electromagnetic radiation field intensity on every side is 10V/m, and the on-the-spot electromagnetic radiation field intensity of circuit breaker actual motion often is greater than 10V/m.Because there are a large amount of numerals and analogue device in intelligent controller inside, to high frequency electromagnetic radiation is quite responsive, when circuit breaker is subjected to extraneous stronger electromagnetic interference, operation irregularity will take place in the electronic devices and components of intelligent controller inside, cause intelligent controller to send wrong instruction and make the circuit breaker misoperation, thereby bring unnecessary loss to the user.We know that the wireless high-frequency signal couples directly on the electronic circuit board by the space, therefore engineers and technicians often are difficult to solve the interference problem of high frequency electromagnetic radiation by the measures such as interference free performance of cabling, layout and the raising components and parts of wiring board, cause development cost to raise, even delay the construction cycle.
As everyone knows, factors such as the metallic cavity of sealing can shield extraneous electromagnetic radiation, but many circuit breakers production firm considers and adopt metallic cavity cost height, and is heavy and yielding, therefore the intelligent controller housing adopts plastic material mostly, so can not shield extraneous electromagnetic radiation.At above-mentioned existing problems, the applicant has passed through useful exploration, finds a way to resolve the problem, and technical scheme described below produces under this background.
Summary of the invention
The purpose of this utility model be to provide a kind of simple in structure, cost is low, can effectively improve the circuit breaker intelligent controller of anti-electromagnetic-radiation ability.
The purpose of this utility model reaches like this, and a kind of circuit breaker intelligent controller comprises housing, is arranged on the electronic circuit board group in the housing, it is characterized in that: have additional the washing layer on the inwall of described housing.
In a concrete real embodiment of the present utility model, front shroud and the back shroud that is located at the plastic casing rear side that described housing comprises plastic casing and is located at the plastic casing front side.
In another specific embodiment of the present utility model, described front shroud, back shroud adopt metal material, have additional the washing layer on the inwall of described plastic casing.
Go back in the specific embodiment of the present utility model, described front shroud adopts plastic material and described plastic casing one injection molded, has additional the washing layer on the inwall of described front shroud equally.
In another specific embodiment of the present utility model, described electronic circuit board group is made of an electronic circuit board at least.
The utility model is owing to adopt technique scheme, not only simple in structure, cost is low, and improved the anti-electromagnetic-radiation performance of intelligent controller, the electromagnetic radiation field intensity that intelligent controller can be born is not less than 30V/m, thereby avoided the electronic devices and components generation operation irregularity of intelligent controller inside, satisfied the application of special occasions.
