12 with the state of extraneous connection.Shift plate 30, shift plate 30 and sliding panel 19 1 are formed on the direction perpendicular to sliding panel 19
Body formed, positioned at the lower section of through-hole 28, main operation axis 12 and the external world are in normally off, need by stirring shift plate 30 downwards,
It drives sliding panel 19 to move downward relative to main operation axis 12, is connected to so that main operation axis 12 be made to switch to extraneous closed state
State.
It further include the electrification display being connect with the earthing switch 9, the electrification display is for receiving the ground connection
The signal that switch 9 exports, to control the energization and power-off of the electromagnet 17.When the electrification display receives high tension loop
When uncharged signal, the locking contact in the electrification display is released, and the electromagnet is powered；When the electrification display
When receiving the signal of high tension loop electrification, the locking contact locking of the electrification display, the electromagnet power-off.It first passes through
Three sensors on earthing switch 9 carry out the detection of high-voltage board mesohigh signal, will test result and pass to electrification display,
By the signals comparator inside electrification display, whether the high tension loop analyzed in high-voltage board is charged, if high tension loop is not
Electrification, can release the locking contact inside electrification display, the wire loop in electromagnet 17 powers on, the electricity of electromagnet
Iron core retracts, so that sliding panel 19 falls, can be switched and be closed a floodgate with operational grounding；If the high tension loop electrification of detection, electrification display
Locking contact locking inside device, the power supply of going the same way of the coil in electromagnet 17 are cut off, and the ferroelectric heart of electromagnet 17 is multiple because of spring
Position effect stops sliding panel 19 to fall, to be unable to operational grounding switch 9, plays anti-misoperation locking function that is, outside stretching electromagnet 17
Energy.At the front door 22 close to cabinet body, 17 ferroelectric heart position of electromagnet, the round tube hole of a diameter 16mm is opened, as tight
The blocking function of electromagnet 17 is released in anxious situation.
The earthing switch 9 passes through the second connecting rod mechanism being set on the main operation axis 12 and the main operation axis 12
Connection, realizes the divide-shut brake of the earthing switch 9 under the turning effort of the main operation axis 12.At the middle part of main operation axis 12
Equipped with front and back partition 10, second connecting rod mechanism is arranged on the main operation axis 12 in the left side of front and back partition 10, the partition 10 in front and back
Right side be equipped with metal axle sleeve 11, since the length of main operation axis 12 is too long, play the role of increasing by 12 rigidity of main operation axis, the
Two link mechanisms include the upper connecting lever 6 connecting with main operation axis 12 and the lower connecting lever that connect with the rotary shaft 24 on earthing switch 9
8 and the connecting rod 7 of upper connecting lever 6 and lower connecting lever 8 is connected, passes through rotation operation handle 23 and control main operation axis 12 and rotate, main operation
Axis 12 drives upper connecting lever 6 and connecting rod 7 and lower connecting lever 8 to move, and drives the rotary shaft 24 on earthing switch 9 to rotate, to realize
The divide-shut brake of earthing switch 9.
Front gate interlocking mechanism is additionally provided on the main operation axis 12, the front gate interlocking mechanism includes being set in the main behaviour
The lever construction making the cam 25 on axis 12 and being connect with the cam 25, in the cam 25 with 12 turns of the main operation axis
When dynamic, the other end of the lever construction and front door opening and closing are connected.Front gate interlocking mechanism is equipped on the right end of main operation axis 12,
Front gate interlocking mechanism includes the cam 25 for being mounted on the left side of auxiliary switch 15, the push plate 14 set on 25 bottom of cam, and perpendicular to
The support rod 26 that push plate 14 is arranged and the hyoplastron 21 for being parallel to the axial direction of main operation axis 12 and being flexibly connected with support rod 26,
Operation handle 23 is rotated, so that main operation axis 12 be driven to rotate, the protrusion of cam 25 is turned to perpendicular to push plate 14, further
Compression support rod 26 downwards, moves upwards the right end of the hyoplastron being flexibly connected with support rod 26 21, hyoplastron 21 is far from support rod
Groove 27 on 26 one end catches on the cross bar on front door 22, to realize the closure at front door；Operation handle 23 is rotated backward,
To drive main operation axis 12 to rotate backward, until the protrusion of cam 25 is parallel to push plate 14, support rod 26 rises, hyoplastron 21
Right end move downward so that the cross bar on the groove 27 on hyoplastron 21 and front door 22 is detached from, realize the unlatching at front door.
It further include the rear door interlocking mechanism of the second end set on the main operation axis 12, the rear door interlocking mechanism includes setting
In the second end reset spring 3, be set in the support 4 in 3 outside of the reset spring and be set to close in the support 4
