[0002] Existing leakage circuit breaker products have the problem in actual application that the dielectric performance test cannot be performed after the product cover is closed, and once the leakage function of the existing product fails, it cannot work normally. Utility Model Content

[0003] The purpose of the utility model is to provide a leakage voltage collection and isolation device. The utility model has the advantage of being able to perform dielectric performance testing in a closed state.

[0004] The technical solution of the utility model is as follows: the leakage voltage acquisition and isolation device includes a cylindrical shell, three limit blocks correspondingly distributed at the front end of the shell, static conductive sheets corresponding to the limit blocks and arranged on the same side of the corresponding limit blocks, a rotating member rotatably sleeved on the middle part of the shell, and three dynamic conductive sheets evenly distributed on the rotating member; the dynamic conductive sheets correspond to the static conductive sheets one by one, and both the dynamic conductive sheets and the static conductive sheets are correspondingly connected to wires; the rotating member can rotate to drive the dynamic conductive sheets to rotate and switch on or off with the static conductive sheets.

[0005] In the aforementioned leakage voltage acquisition and isolation device, a fixed sleeve for installing a rotating part is provided inside the front end of the shell; a limit seat is provided at the front end of the fixed sleeve, and two correspondingly distributed positioning grooves are provided on the limit seat; a positioning protrusion corresponding to the positioning groove is provided at the front end of the rotating part; the positioning grooves correspond to the connection or disconnection of the dynamic conductive sheet and the static conductive sheet respectively.

[0006] In the aforementioned leakage voltage acquisition and isolation device, a mounting structure for installation is provided on the outside of the shell.

[0007] In the aforementioned leakage voltage collection and isolation device, the rotating part includes a rotating handle at the end, a rotating shaft located in the middle of the rotating handle, and a mounting ring seat distributed on the outer extension of the rotating handle corresponding to the rotating shaft; a rotating groove is provided at the end of the rotating handle; and the dynamic conductive sheet is distributed correspondingly on the mounting ring seat.

[0008] In the aforementioned leakage voltage collection and isolation device, the rotating shaft is passed through the middle of the fixed sleeve; a reset spring abutting against the fixed sleeve is sleeved on the rotating shaft, and a spring groove for installing the reset spring is opened at the end of the fixed sleeve.

[0009] In the aforementioned leakage voltage acquisition and isolation device, the mounting structure is a mounting seat, and the mounting seat is T-shaped.

[0010] Compared with the prior art, the present invention includes a cylindrical housing and a rotating member rotatably disposed within the housing. Three static conductive sheets corresponding to the three phases are distributed inside the housing, and three corresponding dynamic conductive sheets are distributed on the rotating member. By rotating the rotating member, the dynamic conductive sheets can be driven to rotate, thereby achieving the connection and separation of the dynamic conductive sheets and the static conductive sheets, completing the switching of the three-phase electricity.

[0011] The present application can be directly installed in a leakage circuit breaker product. The dynamic conductive piece and the static conductive piece are respectively connected to the corresponding electric contacts through corresponding wires. It is only necessary to expose the end of the rotating part. The staff can directly realize the on-off by rotating the rotating part without opening the cover, thereby facilitating the dielectric performance test. At the same time, when the circuit does not require the leakage function and there is a problem with the leakage circuit inside the product, the product also has short-circuit and overload protection functions to enable the product to work normally.

[0012] Therefore, the utility model has the advantages of being able to perform dielectric performance testing in a closed state and selectively shutting off leakage. BRIEF DESCRIPTION OF THE DRAWINGS
