Description
Technical field
The present invention relates to technical field of electricity more particularly to a kind of bulk oil circuits.
Background technology
Breaker is the electric current for referring to close, carry and cut-off under normal loop condition and can close, when defined
Interior carrying and the switching device for cut-offfing the electric current under abnormal loop condition.Breaker is divided into high-voltage circuitbreaker by its use scope
With low-voltage circuit breaker, high-low pressure identification of boundaries is relatively fuzzyyer, and 3kV or more is generally known as High-Voltage Electrical Appliances.
Breaker can be used to distribute electric energy, infrequently start asynchronous motor, to implementations such as power circuit and motor
Protection, when serious overload or short circuit and the failures such as under-voltage occurs in they can automatic shutdown circuit, function is equivalent to molten
The combination that device formula of breaking switchs and crosses underheat relay etc..And parts need not be generally changed after disjunction fault current.Mesh
Before, it has had been widely used.
Electricity generation, conveying, in use, distribution is an extremely important link.Distribution system includes transformer and each
Kind high and low voltage electrical equipment equipment, low-voltage circuit breaker are then a kind of using the electric appliance having a large capacity and a wide range.Breaker generally by contact system, go out
The compositions such as arc system, operating mechanism, buckle releaser, shell.Existing bulk oil circuit easy tos produce more heat when in use, such as
Fruit is radiated not in time, and it is larger to be easy to cause bulk oil circuit loss, and leads to the damage of component, is influencing bulk oil circuit just
Often work, and breaker poor sealing when mounted, are easy to cause the leakage of heat dissipation oil.
Invention content
The purpose of the invention is to overcome the deficiencies of the prior art and provide a kind of bulk oil circuit.
The present invention is achieved through the following technical solutions：
A kind of bulk oil circuit, including bottom plate is fixed using made of cast iron quality, the fixed bottom plate upper end is provided with open circuit
Device shell is respectively arranged with several heat-dissipating pipes on the Shell of circuit breaker both sides, and the Shell of circuit breaker is internally provided with dynamic
Contact, the moving contact upper end are connected with static contact, and the static contact is located inside arc-chutes, the static contact respectively with electricity
Current transformer is connected, and the current transformer is connected with insulating sleeve respectively, filled with disconnected inside the Shell of circuit breaker
Road device oil, the insulating sleeve are connected with fixed cover, and gasket is provided between the fixed cover and Shell of circuit breaker, described
Fixed bottom plate is respectively arranged with cooling fan on both sides.
As the preferred technical solution of the present invention, the gasket is made of elastic material.
It is to be detachably connected between the cooling fan and fixed bottom plate as the preferred technical solution of the present invention.
As the preferred technical solution of the present invention, the cooling fan air draft direction is towards heat-dissipating pipe direction.
Its working principle is that：Bulk oil circuit when in use, when heat-dissipating pipe can after a period of use for bulk oil circuit
By inside Shell of circuit breaker coil windings generate heat distribute in time, at this time cooling fan may be implemented heat pressure distribute,
The loss that coil windings can be reduced in this way, reduces the damage of electronic component, it is ensured that the normal use of bulk oil circuit,
Gasket can improve leakproofness simultaneously, avoid the leakage of breaker oil.
Compared with prior art, the beneficial effects of the invention are as follows：It is disconnected that present invention setting cooling fan can improve heavy wool
The heat dissipation effect of road device avoids the damage of component, it is ensured that the normal use of bulk oil circuit, while having preferable close
Feng Xing.
