By the enforcement of technique scheme, the invention has the beneficial effects as follows: safe to use, can be in time to the starting the arc
Compartment carries out pressure release cooling, is prevented effectively from the generation of the cabinet blasting phenomena caused because of the starting the arc.
Accompanying drawing explanation
Fig. 1 is the structural representation of the high-tension switch cabinet of resistance to electric arc of the present invention.
Fig. 2 is the enlarged diagram at the H position shown in Fig. 1.
Detailed description of the invention
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1 and Figure 2, the high-tension switch cabinet of described resistance to electric arc, including cabinet 1, and it is arranged in cabinet 1
Cable vault 2, breaker chamber 3 and bus-bar room 4, be provided with the row's arc passage 5 being connected with outer row arc region on cabinet 1,
Cable vault's striking passage 6, the row's of connection arc passage 5 and the bus-bar room 4 of connection row's arc passage 5 and cable vault 2 it is provided with in cabinet 1
The breaker chamber striking passage 8 of arc passage 5 and breaker chamber 3 is arranged in bus-bar room striking passage 7 and connection, in cable vault's striking
The exit of passage 6 is provided with the first pressure-relief explosion-proof door 9, is provided with the second pressure release in the exit of bus-bar room striking passage 7 and prevents
Quick-fried door 91, is provided with the 3rd pressure-relief explosion-proof door 92, in the present embodiment, due in the exit of breaker chamber striking passage 8
The mounting means of one pressure-relief explosion-proof door the 9, second pressure-relief explosion-proof door 91 and the 3rd pressure-relief explosion-proof door 92 is the most identical, the most only with first
Illustrating as a example by pressure-relief explosion-proof door 9, the mounting means of the first described pressure-relief explosion-proof door 9 is: the one of the first pressure-relief explosion-proof door 9
Side is hinged with cabinet 1 by rotating shaft 10, and the opposite side of the first pressure-relief explosion-proof door 9 is locked with cabinet 1 phase by explosion-proof bolt 11,
The mounting means simple in construction of above-mentioned pressure-relief explosion-proof door, convenient to install and maintain；In the present embodiment, cable vault's striking passage 6
The outlet of outlet, the outlet of bus-bar room striking passage 7 and breaker chamber striking passage 8 is arranged on the top board of cabinet 1,
The row's arc passage 5 being connected with outer row arc region is arranged on the top of cabinet 1, and the import of row's arc passage 5 covers the most simultaneously
The outlet of cable vault's striking passage 6, the outlet of bus-bar room striking passage 7 and the outlet of breaker chamber striking passage 8, this
Arrangement mode, while ensureing safety in utilization, will not hinder again the normal operating of operator；
The operation principle of the present invention is as follows:
During the use of high-tension switch cabinet, when cable vault 2 produces a large amount of high temperature toxic gas because of the starting the arc, cable vault 2
Interior high temperature toxic gas can first be directly discharged into cable vault's striking passage 6, when the gas pressure in cable vault's striking passage 6 is excessive
Time, the gas in cable vault's striking passage 2 can break through explosion-proof bolt 11 and open the first pressure-relief explosion-proof door 9, makes cable vault's striking
