Description
Technical field
The utility model relates to a kind of feature measurement equipment of vacuum circuit breaker, and especially a kind of velocity characteristic are measured servicing unit.
Background technology
The precision measurement of vacuum circuit breaker product performance is by sensor the product fracture to be linked to each other with measuring equipment, to divide simultaneously, the control line of closing coil and the control line of measuring equipment link to each other, branch, resultant motion information according to contact, that can measure fracture opens data such as distance, contact movement velocity, thereby whether product satisfies request for utilization as can be known.The general volume of measuring equipment that this method requires is bigger, be applicable to fixing operation, move at the scene as fruit product and to go wrong to carry out feature measurement the time, perhaps when carrying out the debugging of pattern testing ground, it is very inconvenient that this method just seems, and the less measuring equipment price of volume compares expensive.
The utility model content
The purpose of this utility model provides a kind of velocity characteristic simple in structure, lower-cost and measures servicing unit.
The technical solution of the utility model is: the vacuum circuit breaker velocity characteristic are measured servicing unit, and this device comprises fixed head and the spinning adjustment swivel nut on the fixed head tapped through hole, adjust the two ends of swivel nut and stretch out fixed head respective panels face; The test lead of adjusting swivel nut has and the concentric pilot hole that is communicated with of swivel nut endoporus, and the pilot hole aperture is less than swivel nut endoporus aperture; Adjust to be coated with in the swivel nut endoporus and be used for the test axle that is connected with test lead, the test lead of test axle passes described pilot hole, and the test axle is slidingly matched with pilot hole, and test spool has the shaft shoulder in the part that is positioned at the swivel nut endoporus; The tail end of adjusting the swivel nut endoporus is installed with the spring top clamping screw, is equiped with spring between spring top clamping screw and test axle.
The tail end of described test axle is provided with test lead connection hole, and the spring top clamping screw is provided with the axial through wires hole that is used to install test lead.
Described fixed head is a L shaped plate towards the bending of adjustment swivel nut test lead, is fixed with on the bending side plate of fixed head for the insulcrete that connects breaker body.
The utility model is a servicing unit that increases between testing mechanical characteristic instrument (another relatively more easy measuring equipment) and tested product, this servicing unit links to each other with breaker body by fixed head, simultaneously and between the product a visible auxiliary fracture is arranged, the variable in distance basically identical of the fracture that forms between this fracture and contact in the product motion process, firm chalaza when the fracture when closing a floodgate by control is like this opened distance and separating brake, can be in product motion, intrinsic numeric that we need is shown from the display screen of mechanical characteristic tester.
The utility model can be combined in Anywhere with the testing mechanical characteristic instrument, the characteristic of measurement products easily, and simple in structure, and cost is very low, easy to use flexible, can be used for the measurement of branch, closing speed and branch, closing time, closing rebound and branch, switching synchronization etc. to product.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is use principle figure of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Vacuum circuit breaker velocity characteristic shown in Figure 1 are measured servicing unit, and this device comprises fixed head 2 and the spinning adjustment swivel nut 4 on the fixed head tapped through hole, adjust the two ends of swivel nut 4 and stretch out fixed head 2 respective panels faces; The test lead of adjusting swivel nut 4 has and the concentric pilot hole that is communicated with of swivel nut endoporus, and the pilot hole aperture is less than swivel nut endoporus aperture; Adjust to be coated with in swivel nut 4 endoporus and be used for the test axle 3 that is connected with test lead, the test lead of test axle 3 passes described pilot hole, and test axle 3 is slidingly matched with pilot hole, and test spools 3 has the shaft shoulder in the part that is positioned at the swivel nut endoporus; The tail end of adjusting the swivel nut endoporus is installed with spring top clamping screw 7, is equiped with spring 5 between spring top clamping screw 7 and test axle 3.Tail end at test axle 3 is provided with test lead connection hole 10, and spring top clamping screw 7 is provided with the axial through wires hole 11 that is used to install test lead.Said fixing plate 2 is the L shaped plates towards the bending of adjustment swivel nut test lead, in order to increase the thickness at fixed head tapped through hole position, is fixed with a thickening plate 6 on the plate face at this position, and tapped through hole extends to thickening plate 6; Be fixed with on the bending side plate of fixed head 2 for the insulcrete 1 that connects breaker body.
In Fig. 2, A, B, C are respectively A phase, B phase, the C phase of product, and the static contact 8 of product A phase, B phase, C phase links to each other by the corresponding jack of lead and testing mechanical characteristic instrument respectively; The moving contact 9 of common port H one end and product links to each other, and the other end links to each other with testing mechanical characteristic instrument common port jack and ground connection; Auxiliary end F one end links to each other with test axle 3 of the present utility model, and the other end links to each other with the auxiliary end of testing mechanical characteristic instrument jack.Like this, when moving contact 9 minutes, when closing, just between moving contact 9 and test of the present utility model axle 3, form an auxiliary fracture.
When product is in the separating brake position (position shown in Figure 2), the test lead of test axle 3 can be adjusted to and moving contact 9 position contacting just, after product closes a floodgate, can measure numerical value such as closing speed, switching synchronization, closing rebound like this by adjusting swivel nut 4; Behind the product combined floodgate, it is the data that need that adjusting adjustment swivel nut 4 makes the distance of opening of the auxiliary fracture of test axle 3 and moving contact 9 formation, can measure numerical value such as opening velocity, separating brake synchronism like this behind the product separating brake.
