Abstract
The utility model relates to a product for measuring the mesh dimension between a movable and a fixed contactors with a contactor box, particularly a device for detecting the mesh depth of a duckbilled contactor, which is positioned inside the contactor box with the movable and the fixed contactors. One end of the movable contactor is connected with a carrier rod which extends horizontally, and the carrier rod is marked with dimension marks; a restoring spring is sleeved on the carrier rod; an outer cover is arranged on the position of the other end of the carrier rod; a through hole through which the carrier rod can be pushed out is arranged on the outer cover. By using the structure, the technical problem that the mesh depth of the movable and the fixed contactors of a switch device with the contactor box can not be measured easily is solved, and the accident rate in the operation of the device can be decreased.
Description
Technical field:
The utility model relates to a kind of product of measuring the dynamic and static contact engagement size of band contact box, particularly a kind of duck-beak type contact depth of engagement pick-up unit.
Background technology:
In the complete industry of high pressure, particularly in the equipment such as cabinet, all the time, the dynamic and static contact depth of engagement of band contact box switchgear is difficult to measure, and dynamic and static contact engagement and the situation of switchgear in actual motion are closely bound up, in case it is not in place that three-phase any is meshed, will cause the accident that to estimate in that total system is in service.
The utility model content:
The purpose of this utility model provides a kind of duck-beak type contact depth of engagement pick-up unit, and the dynamic and static contact depth of engagement that mainly solves band contact box switchgear is difficult to the technical matters of measurement, has reduced the accident rate of equipment operation.
For solving the problems of the technologies described above, the utility model is achieved in that
A kind of duck-beak type contact depth of engagement pick-up unit, be positioned at the contact box that drives contact, static contact, it is characterized in that: the first end of movable contact connects a horizontally extending and mark and is provided with the push rod of dimension mark, be arranged with back-moving spring on this push rod, push rod other end place is provided with outer cover, establishes a perforation for the release of push rod level on this outer cover.
The section of this outer cover is several fonts, and outer cover is fixed on the connecting rod of static contact.
This outer cover is fixed on the connecting rod of static contact by backing plate.
Has the located opening of being used for pin on the push rod of this moving contact.
The junction of this moving contact and push rod has the insulation backplate.
The utility model has the advantages that:
This device designs in reality debugging and operation from switchgear, in conjunction with mechanics principle, simple in structure, can be loaded on the static contact of switchgear, having solved switch cubicle did not have this device in the past and can't measure the problem that the dynamic and static contact of three-phase meshes size, by it in case three sizes that are meshed differ bigger, in the time of can not reaching the engagement size of dynamic and static contact defined, as long as the distance that the measurement push rod is pushed out is left just known the engagement size, thereby carry out the adjustment before the equipment operation, know that three-phase satisfies till the fixed engagement size simultaneously.
This device is mainly used in the complete industry of high pressure (as being applied to KYN18-12 armouring type withdraw-type AC metal switchgear etc.), can detect the engagement of switch cubicle dynamic and static contact when in running order exactly.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Among the figure:
The 1-outer cover; The 2-spring;
The 3-split pin; The 4-plain washer;
The 5-backing plate; The 6-static contact;
The 7-hexagon head bolt; The 8-plain washer;
The 9-spring washer; The 10-backplate that insulate;
The 11-push rod; The 12-contact box;
The 13-moving contact; The 14-slotted pan head screw;
The 15-plain washer; The 16-spring washer.
Embodiment:
See also Fig. 1, it is the structural representation of the utility model duck-beak type contact depth of engagement pick-up unit.As shown in the figure: this device is positioned at the contact box 12 that drives contact 13, static contact 6, moving contact 13 1 ends connect a horizontally extending and mark and are provided with the push rod 11 of dimension mark, be arranged with back-moving spring 2 on this push rod 11, push rod 11 other end places are provided with outer cover 1, establish a perforation for the release of push rod 11 levels on this outer cover 1.
This outer cover 1 is fixed on the connecting rod of static contact 6 by backing plate 5 by slotted pan head screw 14 and plain washer 15.
Have the located opening of being used for pin 3 on the push rod 11 of this moving contact 13, utilize the stationkeeping of this split pin, and accurately obtain the concrete dimension mark on the push rod 11 push rod 11.
This moving contact 13 has insulation backplate 10 with the junction of push rod 11, has guaranteed safety in utilization.
During use, when moving contact 13 when along continuous straight runs is to left movement under external force, drive push rod 11 and push ahead, make spring 2 compressions like this, push rod 11 has the red-label place and is pushed out outside the cover 1, releases distance by measuring, and records the depth of engagement.And the engagement size apart from the dynamic and static contact 13,6 of identification that push rod 11 is advanced left by moving contact 13 just can record the engagement size with measuring appliance like this.
Only being several preferred embodiment of the present utility model in sum, is not to be used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all should be technology category of the present utility model.
