Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of power supply and distribution of electric power systems, and in particular relates to an outdoor permanent magnet box-type high current device. Background Art
[0002] In recent years, due to the needs of economic development, outdoor pole switches have been successfully applied to power systems with their simple structure, few parts, high reliability, precision, long service life, environmental protection, and stable electrical signals. At present, outdoor pole switches are developing in a diversified direction, and the disclosure of numerous patent technologies has promoted the continuous improvement of outdoor pole switch technology. Although these patent technologies are relatively advanced, they are difficult to meet the capacity requirements of customers with large power consumption, which has become the main crux of the current products. The existing technology design is large in size, which wastes raw materials and is cumbersome and labor-intensive. The live body is exposed, which poses a great safety hazard to line operation. It is easy to have excessive resistance in the conductive circuit for a long time due to long-term rain and ultraviolet and air corrosion outdoors, causing heating and line accidents, and equipment operation safety.
[0003] The prior art CN116313580B discloses a permanent magnet mechanism, which reasonably arranges the inner yoke, permanent magnet, outer yoke and moving iron core to share part of the longitudinal space, so that the height of the permanent magnet mechanism is only affected by the height occupied by the electromagnetic coil, thereby reducing the longitudinal size of the permanent magnet mechanism. While reducing the size, the inner yoke, permanent magnet, outer yoke and moving iron core are directly used to form a closed magnetic circuit, so that the length of the closed magnetic circuit is reduced, the magnetic resistance is reduced, and the holding force that meets the use requirements is provided. However, the mechanism is large in size, wastes raw materials, is cumbersome and wastes labor, and the live body is exposed to the outside, which poses a great safety hazard to line operation. Summary of the invention
[0004] In order to solve the above-mentioned problems, the present invention proposes: an outdoor permanent magnet box-type high-current equipment, including a metal shell, a permanent magnet mechanism, an outgoing line, an incoming line, and a high-current circuit breaker, wherein a high-current circuit breaker is installed in the metal shell, the high-current circuit breaker is connected to the permanent magnet mechanism, and the high-current circuit breaker is connected to an external device through an outgoing line and an incoming line.
[0005] Furthermore, the high current circuit breaker controls the closing and opening operations through a permanent magnet mechanism.
[0006] Furthermore, the metal shell is formed in one step.
[0007] Furthermore, the outgoing line and the incoming line are installed in a sealed manner through an inner cone sleeve.
[0008] Furthermore, the metal shell is made of a material with self-heat dissipation function.
[0009] Furthermore, the high-current circuit breaker is a circuit breaker that can meet the maximum capacity of a 10KV transformer.
[0010] The beneficial effects of the present invention are as follows: the present invention solves the defect that the original outdoor pole-mounted switch has a small rated current, which is not conducive to the serious defects of economic development. The high-current circuit breaker is built into a closed shell, which mainly solves the technical problems of large capacity and heat dissipation of the control equipment. Because the high-current equipment will generate a lot of heat during operation, this heat will cause primary insulation damage. The present invention solves this industry difficulty and meets the requirements by its own heat dissipation technology. The use of the present invention can reduce the probability of damaged parts, reduce space, increase reliability and make operation safer and more stable. BRIEF DESCRIPTION OF THE DRAWINGS
