Description

Technical Field

[0001] The invention relates to an electrical switch device, in particular to an auxiliary device of an isolating switch. Background Art

[0002] As an electrical switch device of isolating switch, it undertakes the important task of isolating and switching the circuit in the power or communication distribution system. Therefore, people need to have an intuitive or intelligent grasp of the connection and disconnection status of isolating switch electrical appliances. In order to achieve this purpose, the designers of switch cabinets usually use isolating switches with auxiliary device functions. However, in the current market, the auxiliary devices or auxiliary switches widely used in isolating switches are all in the form of plate type. Figure 1a , Figure 1b The operating buttons of this auxiliary device and auxiliary switch are both arranged on the side of the plate-like structure. If this product is installed on a disconnector with a rotary contact power spindle, it is good. It is easy to install, has a reasonable and reliable structure, and will not increase the installation space of the disconnector in the switch cabinet. However, the result after installation of the disconnector with a slide plate linear motion contact power spindle is not as ideal as the above situation. Since the operating button of the auxiliary device is on the side of the product structure, the installation method is unreasonable and unreliable. The safety space of the disconnector in the switch cabinet is increased a lot. In addition, the wiring terminals of the existing auxiliary device and auxiliary switch are also scattered in each single position. No matter which type of disconnector with a contact power spindle is installed on it, it will cause great trouble to the switch cabinet manufacturer in the installation of the secondary control line. In addition, what is more serious is that the conductor exposed on the outer surface of the wiring terminal causes great safety hazards to the user when operating the disconnector in the cabinet. Summary of the invention

[0003] In order to solve the above problems, the purpose of the present invention is to provide an auxiliary device installed on a disconnector, which, when installed together with the disconnector in a switch cabinet, can bring convenience to the secondary wiring and layout of the assembly personnel of the switch cabinet manufacturer and save the installation space in the switch cabinet, thereby improving the reliability and safety of the operator when operating the switch cabinet in the cabinet.

[0004] In order to achieve the above purpose, one object of the present invention is to provide a novel isolating switch auxiliary device, the isolating switch auxiliary device is in the form of a plate-shaped solid and its operating button should be arranged on the plate-shaped plane, and the operating force direction of the button is perpendicular to the plate-shaped plane.

[0005] Another object of the present invention is to provide a new type of auxiliary device for an isolating switch, wherein the wiring terminals of the auxiliary device of the isolating switch cannot be dispersedly arranged on various surfaces of the auxiliary device shape and the wiring terminals of the wires are exposed on the surface of the auxiliary device. It should be able to facilitate wiring for the assemblers of the secondary lines of the switch cabinet, and improve the safety and reliability of the power grid management personnel when operating the switch cabinet inside the cabinet.

[0006] The above-mentioned objectives will become more obvious through the auxiliary device of the disconnector described below. The auxiliary device of the disconnector includes a base 1, a cover 6, an auxiliary contact module 3 installed in the base 1 and the cover 6, a slider 2, a spring 4, and a socket 5, wherein the spring 4 is installed in the hollow of the rod-shaped square column of the second part 22 of the slider 2. Under the interaction of the slider thrust of the disconnector contact main axis in linear motion and the elastic force of the spring 4 installed in the hollow of the rod-shaped square column of the second part 22 of the slider 2, the slider 2 makes a reciprocating linear motion in the slideway 11, and the corresponding first part 21 of the slider 2 can push the operating button of the auxiliary contact module 3 and open or close the contact, thereby realizing the auxiliary function of connecting and disconnecting the electrical circuit of the disconnector auxiliary device.

DETAILED DESCRIPTION

[0015] See attached Figure 2 , Attachment Figure 5 , Attachment Figure 6 It can be seen from the base 1 part of the disconnector auxiliary device that the part is a three-dimensional sheet after being assembled with the cover 6. The base 1 is provided with a square cylindrical structure slideway 11 perpendicular to the plate surface of the part. The square cylindrical structure slideway 11 has four faces, two of which are provided with openings 111, and the length of the opening 111 is equal to the length of the slideway 11. In addition, it can be seen from the slider 2 that the part is a "T"-shaped three-dimensional structure part, which is composed of two parts. The horizontal part of the "T" is the first part 21 of the slideway 2, and the first part 21 is composed of two identical trapezoidal plates, which are respectively located on both sides of the vertical part 22 of the "T" and are distributed in a mirror image. The vertical part of the "T" is the second part 22 of the slider, and the second part 22 is a hollow three-dimensional rod-shaped square column. The slider 2 is installed in the square cylindrical structure slideway 11 of the base 1. It can slide up and down linearly. At the same time, since the second part 22 of the slider 2 is longer than the cover 6 covering the base, it protrudes on the plane of the sheet-shaped auxiliary device and becomes the operating button of the auxiliary device of the disconnector. When the auxiliary device is equipped with the disconnector, the surface of the cover 6 is close to the shell of the disconnector. When the contact spindle slide plate of the disconnector slides back and forth linearly, the slider 2 can slide back and forth accordingly due to the reaction force of the spring 4. Therefore, this structure achieves the purpose of setting the operating button on the board surface of the auxiliary device. And after being equipped with the disconnector, the installation space used in the switch cabinet is greatly reduced.

The socket 5 is a part with a "six-pin terminal closed integrated design" and can be assembled with a standard "six-hole" integrated socket. It becomes an insulated and sealed secondary line connection conversion accessory. Auxiliary device for isolating switch. The auxiliary contact module 3 is a micro switch part with a "one normally open and one normally closed" design. Two auxiliary contact modules 3 are installed in the base 1, respectively placed on both sides of the slide 11 of the base 1, and the two auxiliary contact modules 3 are firmly connected to the socket 5 with wires. When the slider 2. In addition, the trigger buttons of the two auxiliary contact modules 3 are respectively aligned with the opening 111 of the slide 11 of the base 1, and are tightly connected to the trapezoidal bevel waist of the first part 21 of the slider 2. When the slider 2 moves back and forth, the contacts of the module 3 are also disconnected and connected accordingly. The electrical function of the auxiliary device for isolating switch is realized. The above structure realizes the convenience of wiring for the switch cabinet assemblers and ensures the safety and reliability of the management personnel when operating the switch cabinet in the cabinet.
