Specific embodiment
With reference to the accompanying drawing and specific embodiment is further described the utility model.
As shown in Figure 1, a kind of switchgear equipped with multi-functional arcing channel, including cabinet body, cabinet body include secondary case 1, machine
Structure room 2, preceding bottom compartment 3, upper gas tank 5, lower gas tank 6, cable vault 4 and arcing channel 7.Secondary case 1, mechanism chamber 2, preceding bottom compartment 3 are located at
Cabinet body front, sets gradually from top to bottom；Upper gas tank 5, lower gas tank 6 and cable vault 4 are located at cabinet body rear portion, successively set from top to bottom
It sets, upper gas tank 5 is equipped with upper gas tank rupture disk 8, and lower gas tank 6 is equipped with lower gas tank rupture disk 9.Arcing channel 7 is located at upper gas tank
5, the rear portion of lower gas tank 6 and cable vault 4, comprehensively consider arcing channel leakproofness, stability, intensity and maintenance the problems such as
On, which is connected by screw bolts with cabinet body.The bottom of cabinet body be equipped with air duct 11, air duct 11 and other every
Room connection, cable vault 4 wait the heat distributed in cabinet bodies that can radiate by air duct 11.Cable 10 in cable vault 4 is the bottom of from
Portion picks out.
As shown in Fig. 2, at the top of arcing channel 7 be equipped with pressure relief plate 12, behind be sealing plate 13, side be frame matrix 14, bottom
Portion is equipped with unidirectionally controlled component 15, in conjunction with Fig. 1 it is found that unidirectionally controlled component 15 is between air duct 11 and arcing channel 7.
In conjunction with shown in Fig. 3, Fig. 4, unidirectionally controlled component 15 includes lower cover plate 151, spring assembly 152 and upper cover plate 153, under
By the support connection of spring assembly 152 between cover board 151 and upper cover plate 153, spring assembly 152 can be spring and be placed on double end spiral shell
On bolt, lower cover plate 151, upper cover plate 153 are located at the inside of stud two ends, are equipped among lower cover plate 151, upper cover plate 153
Gap, lower cover plate 151 are equipped with ventilation hole.
The both ends of lower cover plate 151 are equipped with upward lower bending part, and upper cover plate 153 is equipped with downward upper bending part, upper curved
Folding part and lower bending part cooperate, and when upper cover plate 153 pushes, can cover the ventilation hole of lower cover plate 151 is closed.
As shown in Figure 3 and Figure 4, when no arcing occurs, the unidirectionally controlled component 15 in arcing channel 7 can be in the effect of spring
Under it is in the open state, in this state, arcing channel 7 can form a transparent heat dissipation channel.Switchgear
It can give off heat at runtime, it is high thus to will appear in arcing channel 7 top half temperature, and the shape that lower half portion temperature is low
Condition.Under the action of thermal convection, air flowing from bottom to top just will form, and air flowing will take away the heat of switchgear
Amount, to realize the cooling effect to switchgear.
As shown in Figure 5 and Figure 6, when arcing occurs, since unidirectionally controlled component 15 is located under gas tank and cable vault 4
