Embodiment
Below in conjunction with accompanying drawing, by embodiment, the invention will be further described.
As shown in Figure 1 to 9, the high-current switch that a kind of radiating efficiency is high, comprise cabinet 1, cabinet 1 is divided into left cabinet and right cabinet by vertical central dividing plate 2, and the top of left cabinet is breaker chamber 11, bottom is left lower chamber 12 and separated by left horizontal baffle 3 between two Room, right cabinet is divided into upper and lower two parts by a right horizontal baffle 4, wherein the top of right cabinet is provided with again a vertical right clapboard 7 and top is divided into upper left quarter and upper right quarter, the bottom of right cabinet is cable vault 13, upper left quarter is bus-bar room 14, the left side of left lower chamber is provided with venthole plate, wherein venthole plate is shutter 16, the inner side of shutter 16 is provided with metal screen window 17, left horizontal baffle 3 has the perforate 31 being communicated with upper and lower two Room, the cabinet of cabinet 1 withstands on and to be set to protruding upward first with breaker chamber 11 corresponding position and to increase case 6, the first case top 61 of increasing case 6 has intensive through hole 62, the baffler 5 of one end downward bending is provided with in left lower chamber 12, the bending end 51 of baffler 5 is arranged with the positive subtend of the shutter 16 of left lower chamber 12.
The present embodiment also has following improvement on the basis of the above, the cable vault 13 of right cabinet is provided with shutter 16 on right side, the inner side of shutter 16 is provided with metal screen window 17, right horizontal baffle 4 having intensive ventilation hole 41 makes cable vault 13 be connected with the upper right quarter 15 of bus-bar room 14 and right cabinet, the cabinet of described cabinet 1 withstands on and to be set to protruding upward second with bus-bar room 14 corresponding position and to increase case 8, the described second tank wall increasing 8 casees has convection holes 81, case top is corrugated sheet 82; The cabinet of described cabinet 1 withstands on and to be set to the protruding upward 3rd with upper right quarter 15 corresponding position of right cabinet and to increase case 9, and the described 3rd tank wall increasing case has convection holes 91.
See Fig. 1, the outer colder air of high-current switch cabinet enters in switch cubicle through the shutter of left lower chamber, the shutter two place air inlet of cable vault.
The wherein first via, the air that shutter in left lower chamber enters in switch cubicle arrives switch cubicle left lower chamber, due to the lifting effect of left lower chamber's baffler, the perforate of air on left horizontal baffle enters breaker chamber, cools to the handcart be arranged in breaker chamber and dynamic/static contact.Continue upwards to flow after handcart in Air flow breaker chamber and dynamic/static contact, because air now temperature rising becomes high temperature hot gas, so high temperature hot gas is increasing formation stack effect when case is discharged outside cabinet through first, accelerates radiation processes and improve radiating effect.
Wherein the second tunnel, the air entered in switch cubicle through cable vault's shutter is introduced into cable vault, two-way is divided into after cable vault's all parts is cooled, wherein the ventilation hole of a shunt on right horizontal baffle enters bus-bar room cooling bus-bar room all parts, finally increases case from second bus-bar room and discharges outside cabinet; The ventilation hole of another shunt then on right horizontal baffle enters into the upper right quarter of right cabinet, then directly increase case through the 3rd and be discharged to outside cabinet, because air is all heated behind cable vault and bus-bar room, therefore after heating, air is increased when case increased by case and the 3rd by second and all can be formed stack effect, accelerates radiation processes and improves radiating effect.
