[0015] The embodiments of the technical solutions of the utility model will be described in detail below with reference to the drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the utility model, therefore only as an example, and cannot limit the protection scope of the utility model.

[0016] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in the utility model should be the usual meaning understood by the skilled person in the field to which the utility model belongs.

[0017] The frame circuit breaker current characteristic detection equipment structure in the utility model embodiment is as shown in Figures 1 to 3As shown, it comprises a mounting seat 1 and a clamping plate mechanism 2 mounted on the mounting seat 1, the clamping plate mechanism 2 comprises a slide rail 21 arranged on the mounting seat 1 in the up-down direction and four clamping plates 22 arranged on the slide rail 21 in the up-down direction, the four clamping plates 22 are arranged in sequence in the up-down direction, the upper two clamping plates 22 are connected by a first air cylinder 23 and are provided with upper electrodes 25 on two opposite surfaces, the lower two clamping plates 22 are connected by a second air cylinder 24 and are provided with lower electrodes 26 on two opposite surfaces, and a resistance limiting mechanism 3 is arranged below the lowermost clamping plate 22 on the mounting seat 1. In the current characteristic detection equipment of the utility model, the clamping plate mechanism 2 can slide up and down on the slide rail 21. In use, first, the maximum distance between the upper two clamping plates 22 and the lower two clamping plates 22 is kept by the driving of the first air cylinder 23 and the second air cylinder 24, the upper row of conductive plates of the frame circuit breaker is inserted into the gap between the upper two clamping plates 22, and the lower row of conductive plates is inserted into the gap between the lower two clamping plates 22. Then, the upper two clamping plates 22 are driven by the first air cylinder 23 to approach each other to clamp the upper electrodes 25 on the upper row of conductive plates of the frame circuit breaker, and the lower two clamping plates 22 are driven by the second air cylinder 24 to approach each other to clamp the lower electrodes 26 on the lower row of conductive plates of the frame circuit breaker, so that the frame circuit breaker is connected to the detection system. When the resistance limiting mechanism 3 is resisted on the lowermost clamping plate, the clamping plate mechanism 2 is stopped and limited at the lower end limit position. In this embodiment, the structure of the detection equipment is reasonable, the structure of the clamping plate mechanism 2 is relatively simple, the equipment is convenient to assemble and produce, the manufacturing cost is low, and the equipment can be applied to the detection of frame circuit breakers of various specifications.

[0018] As a preferred solution, referring to Figure 2 As shown, in some embodiments, the height of the resistance limiting mechanism 3 is adjustable. Specifically, the resistance limiting mechanism 3 comprises a resistance block 31 and a driving air cylinder 32 driven by the resistance block 31 to move up and down. Under normal circumstances, the clamping plate mechanism 2 slides to the lower end limit position under the action of gravity. In this state, the lowermost clamping plate 22 is resisted on the resistance block 31. When the position of the resistance limiting mechanism 3 is adjusted to be higher, the clamping plate mechanism 2 at the lower end limit position is also correspondingly raised. In the drawings of this embodiment, only one resistance limiting mechanism 3 is given. In actual operation, two or three resistance limiting mechanisms 3 can be arranged. The installation heights of the resistance limiting mechanisms 3 are different, or the strokes of the driving air cylinders 32 in the resistance limiting mechanisms 3 are different, so as to realize multi-gear limiting in the height direction.

[0019] In a further solution of this embodiment, an insulating layer 27 is arranged between the two middle clamping plates 22. The arrangement of the insulating layer 27 can form effective insulation between the two middle clamping plates 22, thereby enhancing the safety performance. The insulating layer 27 can be arranged on one of the two middle clamping plates 22, or insulating layers 27 are arranged on the opposite surfaces of the two middle clamping plates 22. The insulating layer 27 can be an insulating plate.Figure 3 As shown.

[0020] Referring to Figure 1 and Figure 2 As shown, the mounting seat 1 is driven to move in front and back and left and right directions by a two-dimensional driving device, the two-dimensional driving device includes a base 4 driven to move in the front and back directions by a third cylinder 5, the mounting seat 1 is arranged to be movable left and right on the base 4 and is driven by an electric screw rod mechanism 6, that is, the mounting seat 1 can be driven to move accurately in the left and right directions by the electric screw rod mechanism 6, and the base 4 is driven to move forward and backward by the third cylinder 5 to control the clamping plate mechanism 2 to approach and move away from the front frame circuit breaker during current characteristic detection. Exemplarily, the electric screw rod mechanism 6 described above can adopt the following structure: including a screw rod mounted on the base 4, a motor driving the screw rod to rotate and a nut matched with the screw rod, the nut is connected with the mounting seat 1 through a connecting piece 7, guide rails are mounted on the base 4 along the left and right directions, a guide groove is arranged on the mounting seat 1 and is in sliding cooperation with the guide rails, the nut is driven to move along the left and right directions by the motor driving the screw rod to rotate, and then the mounting seat 1 is driven to move relative to the base 4 in the left and right directions by the connecting piece 7.
