Description
Technical field
The present invention relates to low voltage component technical field, and in particular to a kind of breaker.
Background technology
Breaker is the electric current for referring to close, carry and cut-off under normal loop condition and can closed, when defined
Interior carrying and the switching device for cut-offfing the electric current under abnormal loop condition.
Breaker be can be used to distribute electric energy, infrequently start asynchronous motor, and power circuit and motor etc. are carried out
Protection, when serious overloads or short circuit and the failure such as under-voltage occurs in they can automatic shutdown circuit, its function is equivalent to molten
Combination of the disconnected device formula switch with crossing underheat relay etc..And it is latter in disjunction fault current as need not change parts.Mesh
Before, obtain a wide range of applications.
However, often there is following defect in existing breaker in actual use：Many outdoor breakers are due to making
With protection cap is dust-proof, waterproof, radiating effect is poor, and security performance is low, easily causes the situations such as mistrip, and when night trips, it is difficult
Accurately to find its position, the life to people is made troubles.
The content of the invention
In view of the defects and deficiencies of the prior art, the present invention intends to provide one kind is simple in construction, reasonable in design, makes
With convenient breaker.
To achieve the above object, the technical solution adopted by the present invention is：A kind of breaker, including protective cover, breaker sheet
Body, radiator；Breaker body, radiator are located at the inside of protective cover；Radiator is located at the front lower place of breaker body；Open circuit
The side of device body is provided with a radiator fan；The outer casing inner wall of breaker body is provided with fin；Fin and breaker
Shell is integral type structure, is disposably molded by high heat conduction plastics；Described protective cover upper and lower ends are respectively provided with one and prevented
Water swivel；The side of protective cover is provided with radiating groove；Described radiating groove is made up of rectangular heat dissipation hole and radiating port lid；Radiate port lid
Inclination is located above rectangular heat dissipation hole；
Preferably, described radiator is high heat conduction plastic tank radiators；
Preferably, described protective cover is transparent watertight protective cover；
Preferably, described protective cover inwall is sprayed with transparent luminescent powder；
Preferably, the angle of inclination in described radiating port lid and rectangular heat dissipation hole is 30 degree；
Preferably, described radiating port lid is isosceles trapezoid, and the length and width projected to after inclination on rectangular heat dissipation hole all dissipates than rectangle
The length and width of hot hole is big；
After said structure, the present invention has the beneficial effect that：Breaker of the present invention, good heat dissipation effect, water proof and dust proof
Can it is good, security performance is high, when trip at night, can quickly determine its position, and with it is simple in construction, set it is reasonable, be fabricated to
This low advantage.
