Description

Technical Field

[0001] The utility model belongs to the technical field of simulated circuit breakers, in particular to a portable adaptive simulated circuit breaker. Background Art

[0002] The simulated circuit breaker is mainly used for the whole set test of the power system power-off protection device or the complete set of relay protection screens. It can truly simulate the tripping and closing time of the circuit breaker. Generally, the line is required not to be powered off, so the circuit breaker body on site cannot be operated casually. However, the newly equipped circuit breaker controller needs to be tested and all functions are intact before it can be installed on the pole.

[0003] When using existing simulated circuit breakers, most of them directly connect wires to their terminals. The wires lack protection, are easily unstable in connection, and are easily slipped after being touched. Therefore, a portable adaptive simulated circuit breaker is proposed. Utility Model Content

[0004] The purpose of the utility model is to provide a portable adaptive simulation circuit breaker, which can perform secondary compression and fixation on the circuit, improve the stability of the circuit inside the terminal, and effectively avoid the problem of circuit slipping during the test. At the same time, the simulation circuit breaker body and the terminal can be effectively protected during the carrying process, thereby improving the safety of the product when carrying and solving the existing technical problems.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] A portable adaptive simulated circuit breaker comprises: a simulated circuit breaker body, one side of the simulated circuit breaker body is electrically connected to a wiring terminal, one side of the wiring terminal is fixedly connected to a horizontal plate and a limit plate, a surface of the limit plate is integrally formed with a plurality of partitions, and cavities used in conjunction with the wiring terminal are arranged between the partitions;

[0007] A plurality of rotating frames are hingedly connected to one side of the horizontal plate, and a positioning shaft for clamping the conductive wire is fixedly connected to the bottom of each rotating frame. The plurality of positioning shafts are respectively located in the cavity between the partitions. By installing the positioning shaft on one side of the wiring terminal, after the line is connected, the positioning shaft can be moved downward to perform secondary pressing and fixing on the line, thereby improving the stability of the line inside the wiring terminal and effectively avoiding the problem of line slipping during the test process.

[0008] A limiting mechanism is arranged on the top of the transverse plate and is used for positioning the rotating frame.

[0009] As a further solution of the utility model, the limiting mechanism includes a connecting rod and multiple positioning plates, the connecting rod is fixedly connected between the tops of multiple rotating frames, the positioning plates are fixed on the surface of the cross plate, the positioning plates are fan-shaped and have at least two positioning grooves on the circumference, and the circumference of the connecting rod is installed with multiple rubber sleeves used in conjunction with the positioning plates.

[0010] As a further solution of the utility model, a second protective cover for protecting the simulated circuit breaker body is hinged on one side of the simulated circuit breaker body.

[0011] As a further solution of the utility model, a first protective cover for protecting the simulated circuit breaker body is provided on the top of the simulated circuit breaker body. Through the arrangement of the first protective cover and the second protective cover, the simulated circuit breaker body and the terminal blocks can be effectively protected during carrying, thereby improving the safety of the product when carrying.

[0012] As a further solution of the utility model, a support plate is fixedly connected to one side of the simulated circuit breaker body, and the support plate is located below the wiring terminals for supporting the wiring terminals.

[0013] As a further solution of the utility model, fixing holes are provided on both sides of the simulated circuit breaker body.

[0014] As a further solution of the utility model, a rubber pad is bonded to the bottom of the simulated circuit breaker body.

[0015] In the present application, when in use, the circuit breaker body is simulated to be energized, and then the circuit of the test piece is connected to the terminal. When connecting, the circuit is first passed through the cavity between the partitions, and then inserted into the terminal. The circuit is initially fixed by the fixing screws inside the terminal, and then the remaining circuits are connected to the terminal accordingly. After all connections are completed, all the rotating frames are pushed to rotate by the connecting rod, and the rotating frame drives the positioning shaft at the bottom to rotate, and the circuit is pressed by the positioning shaft, thereby completing the secondary clamping and fixing of the circuit. Since the bottom of the rotating frame is inclined, the stability of the circuit clamping and fixing is increased. When the positioning shaft rotates, it drives the rubber sleeve to rotate, and the rubber sleeve uses its own deformation to move from one of the positioning grooves to another positioning groove, thereby completing the limiting of the connecting rod.

[0016] The embodiments of the present invention have the following beneficial effects:

[0017] In the utility model, by installing a positioning shaft on one side of the wiring terminal, after the line is connected, the positioning shaft can be moved downward to perform secondary pressing and fixing on the line, thereby improving the stability of the line inside the wiring terminal and effectively avoiding the problem of line slipping during the test process;

[0018] In the utility model, by providing the first protective cover and the second protective cover, the simulated circuit breaker body and the wiring terminals can be effectively protected during carrying, thereby improving the safety of the product when being carried;

[0019] In the utility model, the circuit can be pressed and fixed for a second time, thereby improving the stability of the circuit inside the terminal block and effectively avoiding the problem of the circuit slipping during the test. At the same time, the simulated circuit breaker body and the terminal block can be effectively protected during carrying, thereby improving the safety of the product when being carried.

[0020] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
