Problems solved by technology

[0008] The purpose of the present invention is to solve the problem of shortening the creepage distance in the rainy environment by using a single porcelain piece for the insulation isolation between the porcelain piece and the resistance band or the resistance piece in the existing chip resistor, which affects the resistance unit in the rainy environment. The insulation performance cannot meet the high-voltage requirements in the rainy environment. A new type of isolation insulation method by resistance bands or resistance sheets is proposed, which can effectively solve the problem of isolation and insulation between resistance bands or resistance sheets. The isolated insulation has the problem of shortening the creepage distance in the rain environment, which can effectively improve the insulation performance of the resistance unit in the rain environment and meet the high voltage resistance requirements of the resistance unit in the rain environment

Embodiment 1

[0035] by attaching Figure 2-5 It can be seen that the present invention relates to a resistance unit with a combination structure of resistance bands, including a support rod 203, a resistance band 201, a whole insulating tube 202 and a conductor 212, through which the support bar 203, the resistance band 201 and the whole insulating tube 202 are combined The two ends of the resistance band 202 are isolated and positioned through the entire insulating tube 202 to form a resistance unit.

[0036] The support rod 203 is a cylindrical metal rod commonly called a tie rod, and there are two support rods 203, which are respectively the first support rod 205 and the second support rod 206; the first support rod 205 and the second support rod The supporting rods 206 are respectively located at the ends 204 of the upper and lower ends of the resistance band 201, and pass through the central hole 207 on the entire insulating tube 202, and the two ends extend out of the entire insulati...

Embodiment 2

[0043] The principle of embodiment two is the same as embodiment one, but the structure of the insulating tube is slightly different, and the different parts are as attached Figure 6-8 As shown, it is a resistance unit with a combination structure of resistance bands, including a support rod 303, a resistance band 301, and an integral insulating tube 302. The resistance unit is formed by combining the support bar 303, the resistance band 301 and the integral insulating tube 302. Its characteristics are The two ends of the resistance band 301 are isolated and positioned through a toothed integral insulating tube 302 .

[0044] It’s just that the overall composite polymer insulation tube 302 is an overall composite polymer insulation tube made of composite polymer materials. The cross-sectional shape of the overall composite polymer insulation tube is a multi-tooth shape, which is convenient for the overall composite polymer insulation tube 302 to connect the resistance band 301...

Embodiment 3

[0049] The principle of the third embodiment is the same as that of the second embodiment. It uses an integral composite polymer insulating tube, but the direction of the "C"-shaped opening on the resistance band is slightly different, and the directions of the openings are perpendicular to each other. Among them One end of the opening is on the top of the resistance band, and the other end is on the side of the resistance band, so that the overall composite polymer insulating tube snaps into the "C" opening on the resistance band more flexibly.

[0050] The cross-section of the overall composite polymer insulating tube can be in various cross-sectional shapes, such as circular, elliptical, arbitrary polygonal or multi-toothed structures (as shown in the attached Figure 9 shown), and has a card slot on the round, arbitrary polygonal or multi-toothed surface.

Abstract

The invention discloses an isolation insulation method with a resistor chip clamped through an integral insulation tube and a resistor unit. The integral insulation tube is adopted to isolate and position resistor strips or resistor chips of the resistor unit; clamping grooves are arranged based on the arrangement interval of the resistor strips or resistor chips of the resistor unit on the integral insulation tube; a semi-opening positioning groove is arranged on the resistor strip or resistor chip at the same time; the integral insulation tube is directly clamped in the semi-opening positioning grooves on the resistor strips or resistor chips, the resistor strips or resistor chips are clamped in the clamping grooves on the integral insulation tube, and through the integral insulation tube, isolation, insulation and positioning are carried out between resistor strips or resistor chips. As the integral insulation tube is directly clamped in the opening grooves on the resistor strips or resistor chips, isolation and positioning of the resistor strips or resistor chips are realized, the resistor strips or resistor chips can be effectively positioned, insulation and isolation between the resistor strips or resistor chips can be effectively realized, the creepage distance of the resistor strips or resistor chips is greatly increased, and the insulation performance of the resistor is improved.
