Description
Technical field
This utility model is related to a kind of vacuum circuit breaker, and specifically a kind of 40.5kv high current indoor high-voltage vacuum breaks
Road device.
Background technology
For indoor product, switch cubicle complexes are always the most frequently used type of service of 40.5kv electric pressure,
So the vacuum circuit breaker supporting with it is also the main flow of Vehicles Collected from Market, but the product of this electric pressure is due to by space and size
Restriction, carry electric current be constantly in a relatively low level, current 40.5kv product joins kyn61-40.5 type switch cubicle
Product only have a kind of this chopper of model of zn85-40.5 (product design construction of other models etc. basic compared with zn85-
40.5), and maximum current maximum accomplishes 2500a, drop-out current accomplishes 31.5ka, the space almost not risen, even when
Under main flow pole also because the restriction of the condition such as temperature rise is exceeded also can only accomplish 2500a.
Content of the invention
The purpose of this utility model seeks to provide a kind of 40.5kv high current indoor high-voltage vacuum circuit breaker, is equipped with and updates
The great-current fixed sealed pole regenerated, by adjusting the frame for movement of chopper itself, makes performance meet high current 3150a and Gao Kai
The ability of disconnected 40ka, expands the use space of chopper, will solve consequent temperature rise under high current service condition simultaneously and ask
Topic is it is ensured that chopper is reliable effectively.
For achieving the above object, this utility model be the technical scheme is that
A kind of 40.5kv high current indoor high-voltage vacuum circuit breaker, it includes vehicle frame, pole and is fixedly connected on
The contact arm on pole top and the contact arm at middle part, vehicle frame is provided with metal framework, and pole is fixedly installed on metal
On framework, pole is internally provided with arc-chutes, upper and lower contact, installs spring mechanism inside metal framework, spring mechanism with
Connected with insulated tension pole between pole, contact arm is connected with upper contact head by electric conductor, contact arm by electric conductor and
Lower contact connects, and pole is arranged above an opening, and electric conductor is fixedly connected with transition face, and transition face is exposed to solid
At sealed pole opening, it is in close contact directly over this transition face and connects fin, around fin, be provided with the tubular of upper and lower opening
Pad.
The lower ending opening of tubular pad is arranged on pole rear fin bottom, and fin section heat is opened by this
Mouth scatters and disappears.
Described contact arm, contact arm nearly pole section are hollow out channel design, are not affecting its electric conductivity and intensity
On the premise of, effectively electric conductor, the partial heat spreading out of in pole can be lost, play auxiliary heat dissipation effect.
When spring mechanism releases energy, divided by the conjunction that insulated tension pole drives pole, realize upper contact head and touch with lower
Conjunction between head divides, thus meeting the function of chopper folding electric current.
The beneficial effects of the utility model are:
This vacuum circuit breaker during normal current-carrying work, flows through the specified high current of 3150a, consequent heat after closing a floodgate
It is delivered to outside pole through electric conductor, after heat reaches transition face, sky is vaporized by the fin at pole top
Among gas, complete the dissipation of heat；Not only act as interconnection function as the upper and lower contact arm being connected with switch cubicle complexes, its
During processing arrange hollow out channel design, also the heat that electric conductor spreads out of can be taken away, further increase chopper operation can
By property.
