Specific embodiment
The total design of the present invention is to be symmetrically installed laser detector in the side of two insulators of disconnecting switch, so that
Observe the contact condition of switch at any time, find that fault trend can be overhauled.Specific embodiment is a lot, is only exemplified by it below
A kind of middle embodiment.
As shown in figure 1, this substation isolating-switch with automatic detection device is on the basis of existing disconnecting switch
On improve and form.The same with existing disconnecting switch：This disconnecting switch also has two shaft-like insulators, i.e. the first insulation
Son 7 and the second insulator 8, the lower end of this two insulators is close together, and upper end is distant, and overall is in " V " shape.First insulation
First bearing seat 5 is passed through equipped with first bevel gear 2 in the bottom of son 7, and second bearing seat 6 is passed through equipped with the in the second insulator 8 bottom
Two bevel gears 3.Two bearing blocks are all fixedly connected with base 4.Visible in conjunction with Fig. 2：First bevel gear 2 and second bevel gear 3 are respectively
The drive bevel gear 1 coaxial with two is meshed.Drive bevel gear 1 is driven by motor.First insulator 7 upper end equipped with first
Contact knife 9 and main contact 11, there is the second contact knife 10 the second insulator upper end.First contact knife 9 and main contact 11 are right with the second contact knife 10
Claim to install, when the first contact knife 9 and main contact 11 are in inside installed insulator with the two the second contact knifes 10, first is tactile
Knife 9 and main contact 11 and the two the second contact knifes 10 are in contact position.
Except that：It is respectively equipped with generating laser 16 and laser pickoff between first insulator and the second insulator
17.Visible in conjunction with Fig. 3：Generating laser 16 and laser pickoff 17 the first contact knife 9 and the main contact 11, second with top respectively
Contact knife 10 is parallel relatively.
During work, drive bevel gear 1 rotates under the drive of motor, drives two absolutely by two bevel gears being meshed
Edge rotates backward, and the first contact knife 9 and main contact 11 rotate with the first insulator 7, and the second contact knife 10 is with the second insulator rotating.
In rotation process, connect when main contact 11 is relative with the second contact knife 10, as close position.When main contact 11 and 10 points of the second contact knife
Open, as divide position.When main contact 11 and the second contact knife 10 are in conjunction position, generating laser 16 is relative with laser pickoff 17,
The laser that generating laser 16 sends is received by laser pickoff 17 completely.Laser pickoff 17 setting light emitting diode be
Send light.When main contact 11 and the second contact knife 10 are in point position, generating laser 16 and laser pickoff 17 deviate, and swash
Optical receiver 17 does not receive the laser signal that generating laser 16 sends, and light emitting diode does not light.So, operating personnel are just
Optical signal can be passed through, accurately judge to close the situation of position, realize the most accurately closing position.Also the event of loose contact can be found in time
Barrier, is keeped in repair in time.
Improve further on the basis of the above, between the lower end of first bevel gear 2 and second bevel gear 3, be provided with infrared temperature
Degree inductor 18.Infrared temperature inductor 18 is in the form of a column, preferably as shown in figure 3, being arranged on the first insulator 7 and the straight up
Base 4 central authorities between two insulators 8.After device is in conjunction position, infrared temperature inductor 18 faces main contact 11.Infrared
The effect of temperature inductor 18 is：During disconnecting switch uses, typically all can produce substantial amounts of heat, particularly main contact 11
Overheated, main contact 11 can be caused to deform so that loose contact is good between the second contact knife 10 and main contact 11, increase resistance, reduce
Electric conductivity.It is mounted with infrared temperature inductor 18 it is possible to receive the infra-red intensity that main contact 11 is radiated, to judge to lead
The temperature of contact 11, whether thus too high to detect the temperature of main contact 11, if too high, to maintenance, troop reports to the police, order inspection
Repair troop to be keeped in repair.
In addition, for the safety ensureing maintenance process, this disconnecting switch is provided with grounded parts.As shown in figure 1, the first insulation
The top of son 7 is provided with grounding static contact 12 and the first contact 13, and grounding static contact 12 and the first contact 13 turn on, the first contact 13
Turn on the first contact knife 9；It is provided with the second contact 14 at the top of the second insulator 8, the second contact 14 and the second contact knife 10 turn on.
Equipped with earthed switch 15 on base 4.Earthed switch 15 can turn on grounding static contact 12 it is also possible to and grounding static contact 12
Disconnect.When disconnecting switch is divided, grounding static contact 12 and earthed switch 15 turn on.When disconnecting switch needs closure,
Grounding static contact 12 and earthed switch 15 are disconnected, you can to guarantee safe operation.
