Description

Technical Field

[0001] This utility model belongs to the technical field of testing equipment, and relates to a testing device, specifically a circuit breaker switch characteristic testing clamping assembly and a switch characteristic testing device. Background Technology

[0002] A circuit breaker is a switching device capable of closing, carrying, and interrupting current under normal circuit conditions, and capable of closing, carrying, and interrupting current under abnormal circuit conditions within a specified time. Circuit breakers are classified into high-voltage circuit breakers and low-voltage circuit breakers according to their application range. The boundary between high and low voltage is somewhat blurred; generally, those above 3kV are considered high-voltage electrical appliances. Circuit breakers can be used to distribute electrical energy, infrequently start asynchronous motors, and protect power lines and motors. When serious overloads, short circuits, or undervoltage faults occur, they can automatically disconnect the circuit. Their function is equivalent to a combination of a fuse switch and over / under-temperature relays.

This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0023] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0024] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0025] like Figure 1 and Figure 2The circuit breaker switch characteristic testing clamping assembly shown mainly includes a support frame 1, a carrier 2, a moving mechanism 3, a lower characteristic test head group 4, a side pushing mechanism 5, and an upper characteristic test head group 6.

[0026] The support frame 1 includes a supporting middle frame 11 and supporting side frames 12 formed on both sides of the supporting middle frame 11 (e.g., assembled from profiles). The supporting middle frame 11 has a horizontally arranged mounting plate 111 in the middle. The supporting middle frame 11 and the supporting side frames 12 adopt conventional structures (e.g., assembled from aluminum alloy profiles), as long as they can effectively install or support other structures. This part of the structure is not the inventive point of this application. In this embodiment, the support frame 1 also includes a plurality of supporting feet 13 installed at the bottom of the supporting middle frame 11 and / or the supporting side frames 12. In this application, a plurality of supporting feet 13 are installed at the bottom of each supporting side frame 12.

[0027] The carrier 2 is slidably mounted on the mounting plate 111 via the moving mechanism 3, and is used to support the circuit breaker group 1' (the circuit breaker group 1' includes a circuit breaker support bracket and multiple circuit breakers mounted on the circuit breaker support bracket). The side-pushing mechanism 5 is mounted on any of the support frame bodies 12 and corresponds to the circuit breaker group 1'; when the circuit breaker group 1' is mounted on the carrier 2, the moving mechanism 3 is first used to move the carrier 2 toward a set of support frame bodies 12, and then the side-pushing mechanism 5 clamps the carrier 2 with the aforementioned support frame body 12 for testing.

[0028] There are two sets of lower characteristic test head groups 4, which are mounted on the mounting plate 111 and located on both sides of the carrier 2, so that the two sets of lower characteristic test head groups 4 are located on both sides of the circuit breaker group 1'. The upper characteristic test head group 6 is movably mounted between the two sets of support frame bodies 12 and located above the circuit breaker group 1'.

[0029] In this embodiment, the moving mechanism 3 includes two first slide rails 31 installed on the upper surface of the mounting plate 111 and spaced apart (the two ends of the first slide rails 31 point to the two sets of support frame bodies 12 respectively), limiting blocks 32 installed on the upper surface of the mounting plate 111 and located at both ends of each first slide rail 31 (to prevent the first slider from falling off the first slide rail 31), and at least one first slider 33 slidably installed on each first slide rail 31 and connected to the bottom surface of the carrier 2 (that is, at least one first slider 33 is installed on one first slide rail 31, and the stability of the sliding mechanism 3 can be improved when the number of first sliders 33 increases). The mounting plate 111 has a large clearance hole 110. The moving mechanism 3 also includes a side plate 34 installed at the clearance hole 110 and vertically arranged, a first rodless cylinder 35 installed on the side plate 34, and a first adapter plate 36 connected to the first rodless cylinder 35 and the carrier 2. When the first rodless cylinder 35 is working, the carrier 2 can be driven to move synchronously on the first slide rail 31 through the first adapter plate 36. The carrier 2 includes a bearing base plate 21 installed on the first slider 33 and two supporting side plates 22 installed on the upper surface of the bearing base plate 21 and cooperating with the circuit breaker group 1'.

[0030] In this embodiment, the side-pushing mechanism 5 includes components installed on any of the support frame bodies 12 ( Figure 1 The system includes a side mounting plate 51 vertically mounted on the right side, multiple guide sleeves 53 (usually two) mounted on the side mounting plate 51, a side push plate 52 located on one side of the side mounting plate 51 facing the carrier 2, two pressing protrusions 56 mounted on the outer surface of the side push plate 52 and spaced apart, multiple guide rods 54 connected at one end to the inner surface of the side push plate 52 and passing through the guide sleeves 53 in a corresponding manner, and a drive cylinder 55 (which can be a hydraulic cylinder, pneumatic cylinder, or electric cylinder, etc.) mounted on the side mounting plate 51 and connected to the side push plate 52. When the drive cylinder 55 is working, it can drive the side push plate 52 to move to the left, thereby causing the pressing protrusions 56 to press against the circuit breaker group 1', thus further improving its clamping stability.

[0031] Each set of lower characteristic test head group 4 includes a pad frame 41 mounted on the mounting plate 111 and located on one side of the carrier 2, multiple sets of first cylinders 42 mounted on the pad frame 41 and spaced apart, a second adapter plate 43 mounted on each set of first cylinders 42, and a first test head 44 mounted on each second adapter plate 43. In this embodiment, there are three circuit breakers, so there are three sets of first cylinders 42, second adapter plates 43, and first test heads 44. When the first cylinders 42 work, they can drive the first test heads 44 to move relative to the circuit breakers and hold them against the circuit breakers for subsequent testing.

[0032] The upper characteristic test head group 6 includes side support plates 61 installed on the inner sides of the two sets of support frame bodies 12, second slide rails 62 installed on each side support plate 61 and horizontally arranged, at least one second slider 64 (same as above) slidably installed on each second slide rail 62, a hanger 63 installed on the second slider 64 and located on the two sets of support frame bodies 12, a second rodless cylinder 65 installed on each side support plate 61 and connected to the hanger 63, multiple sets of second cylinders 66 installed on the hanger 63 and spaced apart, a third adapter plate 67 installed on each set of second cylinders 66, and a second test head 68 installed on each third adapter plate 67. When the second rodless cylinder 65 works, it can drive the hanger 63 to move as a whole on the two second slide rails 62, so that the second test head 68 moves to correspond to the circuit breaker group 1'. Then, the second cylinder 66 works to make the second test head 68 descend and block the circuit breaker for subsequent testing.

[0033] The aforementioned actions can be performed manually, but it is preferable to use existing conventional methods for automated control. However, this is not the inventive point of this application (such as adding a PLC controller to connect the PLC controller to the aforementioned cylinders, drive cylinders, etc., and implementing the control by manually setting parameters; or adding sensors to connect to the PLC controller, using the sensors to detect whether each mechanical structure has moved into place, and then sending control signals to the PLC controller, thereby achieving a higher degree of automated control in existing conventional methods).

[0034] This utility model can also provide a switch characteristic testing device, which includes the above-mentioned circuit breaker switch characteristic testing clamping assembly and a test circuit installed on a set of support frame bodies 12 (the support frame body 12 without the side push mechanism 5), thereby realizing the testing of circuit breaker switch characteristics.

[0035] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
