The outside of operating room.Row's arc channel is made of two square being oppositely arranged row's arc plates 280, row's arc plate 280
Both ends are separately fixed on the two relative side of operating room.In the present embodiment, the quantity in row's arc channel is at least two,
Row described in wherein at least one runs through in arc channel the shell front side face of the operating room, and the behaviour is run through at least one row arc channel
The shell trailing flank for making room, the high temperature and high pressure gas sprayed from the spray arc cylinder can be by the spray arc channels discharge to behaviour
Make outdoor.The right angle channel LXing Paihu in the present embodiment ensures it is possible to prevente effectively from water droplet, dust enter inside operating room
Production safety.
In use, the mounting rack 240 is rotated together with drive shaft 241, and then drives three moving contacts to rotate together,
When 250 one end of the first moving contact and the first plant-grid connection conductive sheet 210 contact, the second moving contact 260 also draws with power supply just
The end thereof contacts of conductive sheet 230 out commonly use power supply at this time and are connected to load.When drive shaft 241 is rotated clockwise to the first dynamic touching
When first 250 other end and second source access conductive sheet 220 contact, third moving contact 270 also draws conductive sheet with power supply just
230 another end in contact, backup power source is connected to load at this time.When moving contact and conductive sheet disengage, moving contact and lead
Due to relatively high apart from close and voltage between electric piece, air ionization between the two can be formed electric arc, electric arc
In the presence of make moving contact and conductive sheet continue keep status of electrically connecting.Electric arc forms hot environment after generating, due to conductive sheet at this time
Inside spray arc cylinder, therefore high temperature makes to spray formation hyperbar inside arc cylinder.With the movement of moving contact, conductive sheet is from spray arc
In a flash, the opening of spray arc cylinder is exposed for cylinder extraction, sprays the high pressure gas inside arc cylinder and quickly sprays from opening, drives electric arc
It sprays together, electric arc quickly extinguishes in swiftly flowing gas, and the electrical connection between moving contact and conductive sheet is so far cut off.
The high-temperature gas of ejection keeps the normal temperature and pressure state inside operating room by the discharge of row arc channel.
Disclosed above is only several specific embodiments of the invention, and still, the embodiment of the present invention is not limited to this, is appointed
