Abstract
The utility model discloses a kind of heat radiating type contact box, and it includes the air intake passage and exhaust vent being arranged on contact box housing;Air intake passage is made up of in the busbar leading-out terminal bottom of contact box housing, air intake passage contact box housing and the air intake semicanal to be poured into an integrated entity with contact box housing, and contact box case top is provided with exhaust vent at static contact；Cold airflow enters contact box from contact box housing bottom air intake passage, is shed from contact box housing upper exhaust vent, takes away the heat of static contact and Mume flower contact contact surface, so as to realize cooling；The contact box its good heat dissipation effect, can guarantee that equipment long-time normal operation especially suitable for 12kV handcart switch cabinet high current operating modes.
Description
Technical field
The utility model belongs to high-tension switch cabinet electric elements technical field, is related to one kind and is opened suitable for 12kV handcart-types
Close a kind of heat radiating type contact box of cabinet.
Background technology
Accompanying drawing 2 is existing prior art 12kV contact box of drawout type switchgear, and its heat dissipation channel is plum blossom on the right side of contact box
The gap of at contact 2 the enters and contact box left side outlet of busbar 7, because these gap spaces are narrow and small, causes air circulation
Speed is slow, and radiating effect is poor, and when electric current is more than 2500A, radiating effect is more undesirable, and temperature easily exceeds national normal value,
Influence equipment normal operation.
The content of the invention
In order to overcome drawbacks described above, the utility model provides a kind of a kind of radiating suitable for 12kV handcart switch cabinets
Type contact box.
A kind of heat radiating type contact box described in the utility model includes the plum inside contact box housing 1 and contact box housing 1
Flower contact 2, the static contact 3 overlapped with Mume flower contact 2 and the busbar 7 being connected with static contact 3, set in the bottom of contact box housing 1
There is air intake passage 8, top is provided with exhaust vent 5.
Effect of the present utility model is achieved by the following technical solution：The principle flowed up according to thermal current,
The bottom of contact box housing 1 opens up air intake passage 8 close to the leading-out terminal of busbar 7, on the top of contact box housing 1 at static contact 2, opens
Set out air holes 5；Cold airflow enters contact box from the bottom air inlet passage 8 of contact box housing 1, from the top exhaust vent 5 of contact box housing 1
Place sheds, and takes away static contact 3 and the partial heat on Mume flower contact 2, so as to realize cooling, by reducing operating ambient temperature,
The service life and reliability of switch cubicle electric elements are improved, ensures equipment long-time normal operation.
Air intake passage 8 on the contact box housing 1 is located at the leading-out terminal bottom of busbar 7 of contact box housing 1, air intake passage
8 are made up of contact box housing 1 and the air intake semicanal 9 to be poured into an integrated entity with contact box housing 1, the length of air intake passage 8 according to
Creep age distance requires to determine electrical body as defined in Its Relevant Technology Standards over the ground.Air intake passage 8 must should meet electrical body over the ground
The safety requirements of creep age distance, maintain existing contact box appearance and size change little again, be easy to make and similar with other tactile
Head cartridge used interchangeably；The set-up mode of the utility model contact box air intake passage 8 is well positioned to meet above-mentioned security and exchange
Property two requirement.
Reinforcement 4 is provided with exhaust vent 5 in the inside of contact box housing 1, to make up contact box housing 1 because setting out
Air holes and the overall construction intensity weakened.
Preferably, full skirt 6 is provided with exhaust vent 5 in the outside of contact box housing 1, to meet that electrical body climbs electricity over the ground
Required distance.
This programme contact box housing uses APG pouring technologies, and one-shot forming, compared with conventional contact box housing, profile does not have
Dramatically increase, convenient installation.
A kind of thermal diffusivity contact box described in the utility model, simple in construction, good heat dissipation effect, there is good radiating work(
Can, apply in 12kV handcart switch cabinets, when electric current is more than 2500A, radiating effect is ideal, and temperature is marked less than country
Quasi- value, can guarantee that equipment long-time normal operation.

Embodiment
It is below a specific embodiment of the present utility model, is described further with reference to Figure of description.
A kind of heat radiating type contact box as shown in figures 1-6, its contact box housing use APG techniques, one-time cast-forming.
Air intake passage 8 is arranged on the leading-out terminal bottom of busbar 7 of contact box housing, and air intake passage 8 is by contact box housing 1 and and contact box
The air intake semicanal 9 that housing 1 pours into an integrated entity forms, and fresh air inlet passage length is according to electrical body creep age distance correlation technique mark over the ground
Alignment request is set；Exhaust vent 5 is set at the top of contact box housing 1, creep age distance is increased with full skirt 6, while increases reinforcement 4,
Prevent the remitted its fury at exhaust vent 5 of contact box housing 1.
The present embodiment contact box, simple in construction, appearance and size is compared with conventional same specification contact box appearance and size without obvious
Change, can realize used interchangeably with normal contacts box, improve standardization level, reduce production cost.
The present embodiment contact box good heat dissipation effect, there is good heat sinking function.Apply in 12kV handcart switch cabinets, when
When electric current is more than 2500A, radiating effect is ideal, and temperature is less than national normal value, improves the use of switch cubicle electric elements
Life-span and functional reliability, it can guarantee that equipment long-time normal operation.
