Description
Technical field
The utility model relates to a kind of isolating switch, the high voltage isolator that particularly a kind of rotary drill high voltage control cabinet is used.
Background technology
The GN6-10 high voltage isolator is auxiliary products important in the electrical control equipment; The complete control panel of former rotary drill all designs by the 6KV electric pressure; At present and along with the development of mine construction, a lot of local electric pressures have risen to 10KV, because the workbench of rotary drill is less; So the volume to high-voltage board limits; Adopt the conventional high voltage isolator of domestic 10KV level to be installed in the high-voltage board very difficulty, electric clearance and creepage distance also satisfied not requirement, cause dielectric test between phase and phase, produce flashover between electric conductor and the shell.
Summary of the invention
In order to solve the above-mentioned technical problem that high voltage isolator exists, the utility model provides that a kind of compact conformation, volume are little, good electric property, installation and maintenance are convenient, safety high voltage isolator reliably again.
The technical scheme that the utility model solves the problems of the technologies described above is: comprise framework, fixed contact, moving contact, blade, insulator, insulated tension pole, spheric washer, main shaft, crank; Have six insulators and be fastened on the framework, fixed contact is loaded on three insulators in top; Moving contact, strutting piece, blade, spheric washer through screw rod, nut be linked together form moving contact component, be contained on three insulators of bottom; Main shaft is installed on the framework, be welded with connecting lever on the main shaft and link to each other with an end of insulated tension pole, the other end of insulated tension pole through round pin with regulate head and connect with blade; One end of crank is by taper pin and the bolted right-hand member at main shaft, and the other end connects with the connecting rod of high voltage control operating mechanism cashier's office in a shop.
The thickness of said spheric washer is 5mm.
The beneficial effect of the utility model is: the contact hold down gag of the utility model has adopted the hold down gag of the spheric washer that processes with spring steel band; Make the contact-making surface of contact and blade that enough contact pressures arranged; Reduced contact resistance; Shorten the length of screw rod, made electric clearance become big, guaranteed the functional reliability of high voltage isolator; Secondly the utility model have also that compact conformation, volume are little, good electric property, convenient, safe and reliable, the cheap advantage of installation and maintenance.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the left view of the utility model.
Embodiment
From Fig. 1, shown in Figure 2, the utility model mainly is assembled by framework 3, fixed contact 1, moving contact 14, blade 13, insulator 2, insulated tension pole 12, spheric washer 4, main shaft 7, crank 9.
Six insulators 2 on the high voltage isolator are fastened on the framework 3; Fixed contact 1 is contained on the insulator 2 on top; Moving contact 14 is contained on the insulator 2 of bottom with strutting piece 15, and the spheric washer 4 that thickness is 5mm is equipped with in the both sides of blade 13, through screw rod and moving contact 14 and strutting piece 15 be linked together the composition moving contact component; Through compressing spheric washer 4 with the adjustment of nut; Make it produce sizeable contact pressure, one of two blades, 13 front end therebetween have lining 8, can be well and fixed contact 1 closure to guarantee blade 13.Main shaft 7 is installed on the framework 3; Connecting lever 10 on the main shaft 7 and an end of insulated tension pole 12 with pin 11 be linked together; The other end of insulated tension pole 12 through round pin 5 with regulate 6 and connect with blade 13; One end of crank 9 is by taper pin 16 and the right-hand member of bolted at main shaft 7, and the other end connects with the connecting rod of operating mechanism.
During the utility model work; High voltage isolator is fixed on the mounting rail of high-voltage board; When pulling the CS6 operating mechanism handle that is installed on the high-voltage board housing, when the connecting rod of operating mechanism drive crank 9 rotated, this moment, main shaft 7 also rotated; Connecting lever 10 on the main shaft 7 is also followed rotation; The blade 13 that causes connecting lever 10 to promote insulated tension poles 12 motions and drive in the moving contact component rotates around the center, hole of strutting piece 15, this moment blade 13 along with producing closed between the direction that rotatablely moves and the fixed contact 1 or separate, thereby realize the connection and the disjunction of high voltage isolator.
Because the utility model on the basis of 6KV high voltage isolator, changes the version that former compression of leaning on two springs to produce at contact pressure, the spheric washer that adopts spring steel band to process substitutes spring.The pressure area that spheric washer produces is big, and the contact pressure that contact bears is even, because the contact area of contact and blade increases, makes the contact resistance of contact-making surface reduce; And because the thickness of spheric washer has only 5mm; And the length of 6KV high voltage isolator upper spring is 22.5mm, so the length of screw rod shortens to 65mm from original 95mm, makes distance between phase and phase increase greatly; Be that electric clearance becomes greatly; Thereby improved the electric property of high voltage isolator greatly, made the 32KV/1min dielectric test of 10KV level high voltage isolator pass through smoothly, do not had puncture and flashover phenomenon.
