Abstract
The utility model discloses a static contact system of a high-tension switch cabinet, which comprises a contact box, a static contact and a heat slug. The contact box is cylindrical, the static contact is arranged in the contact box, the heat slug is flat, the upper end of the heat slug penetrates out from the top of the contact box, and the lower end of the heat slug is fixed on the inner side of the contact box via a bolt and the static contact. By the aid of the technical scheme, the static contact system effectively reduces heat release by means of increasing conductive sections of conductors and reducing contact resistors connected among the conductors, and simultaneously increases heat dissipation area of the conductors, particularly heat dissipation area of the conductors outside the contact box, thereby greatly strengthening heat dissipation effect, and effectively reducing operation temperature of the total static contact system.
Description
Technical field
The utility model relates to a kind of fixed contact system of high-tension switch cabinet.
Background technology
The heating problem of electric equipment is the important research aspect of power industry always, and described herein is the fixed contact system heating problem of high-tension switch cabinet.By switch cubicle long-time running record and all kinds of temperature rise test record are researched and analysed, the caloric value of fixed contact system when work is much larger than other conductive components of switch cubicle, the switch cubicle of big electric current particularly, this problem is more serious, can have a strong impact on the safe operation of equipment like this.
All kinds of versions of domestic present application, it mainly is that contact box is installed on the dividing plate of switch cubicle, general switch cubicle divides two each 3 distribution of row up and down, fixed contact is installed in the contact box, copper bar passes the duckbill through hole of contact box, insert the fixed contact bottom, and utilize the bolt fixing copper bar simultaneously that fixed contact is installed.Because consider the problem of insulation, contact box inside is deep, and does not have ventilation hole, so heat is difficult to distribute, in addition, because the copper bar evenness is general and problem such as distortion is installed, contact resistance is also bigger.These two factors cause the caloric value of fixed contact system when work other conductive components much larger than switch cubicle.
The utility model content
Technical problem to be solved in the utility model provides a kind of fixed contact system of high-tension switch cabinet, and the operating temperature of fixed contact system is obviously reduced.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: the fixed contact system of high-tension switch cabinet, comprise contact box, fixed contact, described contact box is cylindric, described fixed contact is located in the contact box, also comprises radiating block, and described radiating block is a flat, the upper end of described radiating block is passed by the top of described contact box, and the lower end of described radiating block is fixed in the inboard of described contact box together by bolt and described fixed contact.
The centre of described radiating block is provided with heat sink strip, has increased area of dissipation, strengthens radiating effect.
Described fixed contact is provided with five counterbores, can increase conductive section like this and improve thermal capacitance.
The utility model is owing to having adopted technique scheme, owing to the contact resistance that has increased each conductor conductive section and reduced to connect between the conductor effectively reduces thermal discharge; Increase the area of dissipation of conductor simultaneously, particularly the conductor area of dissipation of contact box outside has strengthened radiating effect greatly, and the operating temperature of whole fixed contact system is effectively reduced.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
Figure 1 shows that the fixed contact system of the utility model high-tension switch cabinet, comprise contact box 1, fixed contact 4, described contact box 1 is cylindric, integral body is made by insulating material, and described fixed contact 4 is located in the contact box, also comprises radiating block 2, described radiating block 2 is a flat, stub end and little head end are divided in two ends, and the microcephaly holds width the same with the copper bar that links to each other, and are convenient to connect; Stub end need insert in the contact box.Stub end has five holes, so that be connected with fixed contact, little head end has four holes, so that be connected with copper bar, the upper end of described radiating block 2 is passed by the top of described contact box 1, and the lower end of described radiating block 2 is fixed in the inboard of described contact box 1 together by bolt 3 and described fixed contact 4.As shown in Figures 2 and 3, the centre of described radiating block 2 is provided with heat sink strip 5, and with insulating material heat sink strip 5 is covered.As shown in Figure 4 and Figure 5, described fixed contact 4 is provided with five counterbores 6.
Operation principle: radiating block 2 is global copper parts, its surface area is big and evenness is relatively good, be connected with copper bar or fixed contact 4 connects and all can reduce contact resistance, the design that fixed contact 4 changes original big counterbore changes five little counterbores into, increase conductive section like this and improve thermal capacitance, utilize five bolts 3 fixedly fixed contact 4 and radiating block 2 also can reduce contact resistance, these can reduce caloric value; Radiating block 2 stretches out contact box 1 partial design heat sink strip, has increased area of dissipation, strengthens radiating effect.In sum, utilize and to reduce caloric value and to increase radiating effect that to control temperature too high.
