The utility model is that the technical solution problem mainly realizes through following technical scheme: the switch cubicle that a kind of fail safe is higher, comprise cabinet, and the bottom of cabinet is provided with the ground connection main bus bar; The inner space of cabinet is separated into four unit by dividing plate, is respectively circuit breaker cart chamber, relay control room, cable vault and bus-bar room, the indoor guide rail that is provided with circuit breaker cart and matches with circuit breaker cart of circuit breaker cart; Be provided with earthed switch and cable in the cable vault; The top of cable vault is provided with current transformer, and current transformer is connected with cable, is provided with main bus bar and bus casing in the bus-bar room; Main bus bar is fixed through little bus of branch and fixed contact box; Be provided with static contact head device in the fixed contact box, said relay control room is positioned at the top of circuit breaker cart chamber, and the bottom of circuit breaker cart chamber is provided with the little bus duct of control; Bus-bar room is positioned at the top of cable vault, also is provided with the mesohigh potential indicator that is connected with cable in the said cable vault.
Also be provided with lightning arrester in the said cable vault, lightning arrester is connected with earthed switch.
The top of said cabinet is provided with pressure relief device.When circuit breaker or bus generation internal fault, follow the appearance of electric arc, the switch cubicle air pressure inside raises, and pressure relief device is opened, release pressure and drainage gas.
Said pressure relief device has 3 and lay respectively at the top of circuit breaker cart chamber, bus-bar room and cable vault.
The utility model compared with prior art has the following advantages and beneficial effect:
When (1) bus of the utility model passes through the switch cubicle dividing plate, with bus casing bus is fixed, when electric arc was broken down in switch cubicle inside, restriction accident well spread to adjacent cabinet, and had ensured the mechanical strength of bus.
(2) top of the utility model is provided with pressure relief device, and when the switch cubicle air pressure inside raise, release pressure, drainage gas avoided causing the damage of operating personnel and switch cubicle soon.
(3) the utility model is provided with the mesohigh potential indicator on the basis of switch cubicle in the past, is used to treat the survey time road and carries out the real-time voltage test, and the charged state in prompting mesohigh loop has been avoided operating personnel careless and inadvertent, thereby avoided causing the accident.
