Abstract
The utility model discloses a radiator for an air chamber inner pole. The radiator comprises a horseshoe-shaped installation surface provided with installation holes. One side of the installation surface is provided with adjacent longitudinal radiating ribs. The radiator for the air chamber inner pole, which is of a compact structure, is directly installed in the position of a flexible coupling of a moving terminal of a circuit breaker and directly contacts with the flexible coupling, thereby effectively enabling heat generated in the position with maximum generated heat to be radiated out and effectively lowering the local temperature rise. The radiator is installed in the positions of a conductive clamp and the flexible coupling of the circuit, where the temperature rise is relatively high, so that the heat radiation area is enlarged; and the radiating ribs extend outwards simultaneously so that the local temperature rise can be well improved with pertinency.
Description
Technical field
The utility model relates to a kind of radiator, relates in particular to pole radiator in a kind of air chamber.
Background technology
Cubicle Gas-Insulated Switchgear has the advantages such as volume is little, and reliability is high, and adaptive capacity to environment is strong, thereby has obtained in recent years developing rapidly.But because major loop is sealed in air chamber fully, thereby its radiating condition extreme difference, when electric current reaches 2000A when above, the temperature rise of equipment can't well solve.Especially circuit breaker moved end conducting rod and the position that is flexible coupling, space is little, and faying surface is intensive, and caloric value is large, and local temperature is high, and electric current can't reach higher requirement.In the major loop pole, conductive clip and (the being the moving conductive rod place) faying surface that is flexible coupling are many, and caloric value is large, and radiating condition is poor.
In industry, a lot of producers adopt the mode of fin being installed in the air chamber surrounding sidewall outside, although this mode can play certain effect, affect cabinet cabinet, increased the profile of equipment, and circuit breaker local temperature rise can not get basic solution.In addition at the general also installation of heat radiator of air chamber inner breaker, but generally be arranged on the position, quiet end of circuit breaker or the bus that breaker outgoing line connects, all less than directly contacting with being flexible coupling, the heat radiation of circuit breaker moved end all do not had to great role.
The utility model content
The purpose of this utility model is to provide a kind of compact conformation, effective pole radiator in a kind of air chamber of increasing heat radiation area.
For achieving the above object, the technical scheme that the utility model is taked is:
Pole radiator in a kind of air chamber, comprise shape of a hoof installed surface, and described installed surface is provided with installing hole, and a side of described installed surface is provided with adjacent vertical radiating ribs.
Described installing hole has three.
Described radiating ribs comprises the rectangle radiating ribs of both sides and middle red flag type radiating ribs.
Described red flag type radiating ribs is to increase a little rectangle on the top of described rectangle radiating ribs.
Described rectangle radiating ribs and red flag type radiating ribs sharp corner are the fillet smooth transition.
Described rectangle radiating ribs is two, and described red flag type radiating ribs is six.
Scribble respectively black heat radiation paint on described rectangle radiating ribs and red flag type radiating ribs.
Pole radiator in the air chamber that adopts the utility model to provide, compact conformation, be directly installed on the position that is flexible coupling, circuit breaker moved end, directly contacts with being flexible coupling, and can effectively the dissipation of heat at the maximum position that generates heat be gone out, and effectively reduces local temperature rise.Because this radiator is installed on the higher circuit breaker conductive clip of temperature rise and the position that is flexible coupling, increased area of dissipation, radiating ribs stretches out simultaneously, makes targetedly local temperature rise obtain good improvement.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Structural profile schematic diagram when Fig. 2 is the utility model installation.
In figure, the 1-installed surface, the 2-installing hole, 3-rectangle radiating ribs, 4-red flag type radiating ribs, 5-is flexible coupling, the 6-pole.
Embodiment
Below in conjunction with specific embodiment and accompanying drawing thereof, the utility model is described in further detail, but execution mode of the present utility model is not limited to this.
As shown in Figure 1, pole radiator in the air chamber that the utility model provides, comprise shape of a hoof installed surface 1, offers the installing hole 2 that three diameters are 9mm on installed surface 1, is convenient to the installation of radiator.One side of installed surface 1 is welded with eight adjacent vertical radiating ribs, and two radiating ribs of both sides are rectangle radiating ribs 3, and middle six is red flag type radiating ribs 4, and red flag type radiating ribs 4 is to increase a little rectangle on the top of rectangle radiating ribs 3.The sharp corner of rectangle radiating ribs 3 and red flag type radiating ribs 4 has all been led the fillet smooth transition.Scribble respectively black heat radiation paint on rectangle radiating ribs 3 and red flag type radiating ribs 4, increase the heat loss through radiation amount.
As shown in Figure 2, in the air chamber that the utility model provides pole with radiator, when installing and using, installed surface 1 is connected to and is flexible coupling on 5 by three installing holes, 2 use bolts.Every phase pole 6 is installed upper and lower two groups of radiators, and the radiating ribs of radiator is vertically arranged, extends to the upper and lower opening place of pole 6 simultaneously.This version, the gap between radiating ribs has formed vertical air channel one by one, at pole 6 opening parts, forms good convection current, and the heat that 5 places that effectively will be flexible coupling produce is taken out of.
The be flexible coupling excellent heat conductive performance of 5 copper products used of utilization, can will be flexible coupling and the heat at conductive clip place conduct on the radiating ribs of radiator 1
.scribble pitch-dark heat radiation paint on radiating ribs, pitch-dark heat radiation paint has very strong thermal radiation capability, and the heat that is gathered in this place is outwards distributed, and has effectively improved the temperature rise of this part.
By 5 positions that are flexible coupling at pole 6, pole radiator in air chamber is installed, the current capacity of whole pole 6 is improved greatly, the rated current of 2000A can be brought up to 2500A.
Above-described is only preferred embodiment of the present utility model, does not limit to the utility model.Should be understood that for the person of ordinary skill of the art, under technology enlightenment provided by the utility model, can also make other equivalent modifications and improvement, all can realize the purpose of this utility model, all should be considered as protection range of the present utility model.
