metal-enclosed switchgear (hereinafter referred to as \"switchgear\") is a complete set of distribution equipment for 20kV three-phase AC 50(60)Hz single busbar and single busbar sectional systems. It is mainly used in power plants, medium and small generator power supply, distribution for industrial and mining enterprises, and secondary substations in power systems for receiving and transmitting electricity, as well as starting large high-voltage motors. It is used for control, protection, and monitoring. This switchgear has the \"five-proof\" interlocking functions, which prevent the withdrawal of the circuit breaker under load, prevent mistaken opening or closing of the circuit breaker, prevent closing the circuit breaker when the grounding switch is in the closed position, prevent entering live compartments by mistake, and prevent faulty closing of the grounding switch when energized. It can be equipped with the VS1-24 type vacuum circuit breaker developed and trial-manufactured by our company, making it an excellent performance distribution device. The product complies with standards such as GB 3906, GB\/T 11022, and IEC 60298.<\/p>\n  <\/div>\n<\/div>\n\n\n<div class=\"kyn24-card\">\n  <h2 class=\"kyn24-section-title\">Technical Parameters<\/h2>\n  <div class=\"kyn24-table-wrap\">\n    <table class=\"kyn24-param-table\">\n      <thead>\n        <tr>\n          <th>Name<\/th>\n          <th style=\"width:50px;\">Unit<\/th>\n          <th>Value (Matched circuit breaker VS1-24)<\/th>\n        <\/tr>\n      <\/thead>\n      <tbody>\n        <tr><td>Rated voltage<\/td><td class=\"unit-col\">kV<\/td><td>24<\/td><\/tr>\n        <tr><td>1min power frequency withstand voltage<\/td><td class=\"unit-col\">kV<\/td><td>(50)65<\/td><\/tr>\n        <tr><td>Rated impulse withstand voltage (peak)<\/td><td class=\"unit-col\">kV<\/td><td>125<\/td><\/tr>\n        <tr><td>Rated frequency<\/td><td class=\"unit-col\">Hz<\/td><td>50(60)<\/td><\/tr>\n        <tr><td>Rated current<\/td><td class=\"unit-col\">A<\/td><td>630, 1250, 1600, 2000, 2500, 3150<\/td><\/tr>\n        <tr><td>Rated current of branch busbar<\/td><td class=\"unit-col\">A<\/td><td>630, 1250, 1600, 2000, 2500<\/td><\/tr>\n        <tr><td>Rated short-time withstand current<\/td><td class=\"unit-col\">kA<\/td><td>16, 20, 25, 31.5<\/td><\/tr>\n        <tr><td>Rated peak withstand current<\/td><td class=\"unit-col\">kA<\/td><td>40, 50, 63, 80<\/td><\/tr>\n        <tr><td>Rated short-circuit duration<\/td><td class=\"unit-col\">s<\/td><td>4<\/td><\/tr>\n        <tr><td>Protection level<\/td><td class=\"unit-col\">\u2014<\/td><td>The enclosure is IP4X, it is IP2X when the compartment door and circuit breaker chamber door are opened<\/td><\/tr>\n        <tr><td>Mass<\/td><td class=\"unit-col\">kg<\/td><td>800, 1000 (Rated current above 1600A)<\/td><\/tr>\n      <\/tbody>\n    <\/table>\n  <\/div>\n<\/div>\n\n<div class=\"kyn24-card\">\n  <h2 class=\"kyn24-section-title\">Structure Diagram<\/h2>\n  <div class=\"kyn24-diagram\">\n    <div class=\"kyn24-diagram-legend\">\n      <div class=\"kyn24-legend-title\">Components<\/div>\n      <div class=\"kyn24-legend-item\"><span class=\"kyn24-legend-num\">1<\/span><span>Wall bushing<\/span><\/div>\n      <div class=\"kyn24-legend-item\"><span class=\"kyn24-legend-num\">2<\/span><span>Analog primary diagram<\/span><\/div>\n      <div class=\"kyn24-legend-item\"><span class=\"kyn24-legend-num\">3<\/span><span>Nameplate<\/span><\/div>\n      <div class=\"kyn24-legend-item\"><span class=\"kyn24-legend-num\">4<\/span><span>Illuminating lamp<\/span><\/div>\n      <div class=\"kyn24-legend-item\"><span class=\"kyn24-legend-num\">5<\/span><span>Main busbar<\/span><\/div>\n      <div class=\"kyn24-legend-item\"><span class=\"kyn24-legend-num\">6<\/span><span>Contact box<\/span><\/div>\n      <div class=\"kyn24-legend-item\"><span class=\"kyn24-legend-num\">7<\/span><span>Current transformer<\/span><\/div>\n      <div class=\"kyn24-legend-item\"><span class=\"kyn24-legend-num\">8<\/span><span>Primary cable<\/span><\/div>\n      <div class=\"kyn24-legend-item\"><span class=\"kyn24-legend-num\">9<\/span><span>Earthing busbar<\/span><\/div>\n      <div class=\"kyn24-legend-item\"><span class=\"kyn24-legend-num\">10<\/span><span>Secondary interlocking assembly<\/span><\/div>\n      <div class=\"kyn24-legend-item\"><span class=\"kyn24-legend-num\">11<\/span><span>Valve mechanism<\/span><\/div>\n      <div class=\"kyn24-legend-item\"><span class=\"kyn24-legend-num\">12<\/span><span>Handcart of circuit breaker<\/span><\/div>\n      <div class=\"kyn24-legend-item\"><span class=\"kyn24-legend-num\">13<\/span><span>Insulator<\/span><\/div>\n      <div class=\"kyn24-legend-item\"><span class=\"kyn24-legend-num\">14<\/span><span>Heater<\/span><\/div>\n      <div class=\"kyn24-legend-item\"><span class=\"kyn24-legend-num\">15<\/span><span>Framework of cabinet body<\/span><\/div>\n    <\/div>\n    <div class=\"kyn24-diagram-img\">\n      <img decoding=\"async\" src=\"https:\/\/haochengcompany.com\/wp-content\/uploads\/2026\/06\/124578.webp\" alt=\"KYN28-24 Structure Diagram\">\n    <\/div>\n  <\/div>\n<\/div>\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>","protected":false},"excerpt":{"rendered":"<p>Home \u9875\u9762 General Purpose Armored Withdrawable Switchgear Customizable The KYN28-24(Z) series armored withdrawable AC metal-enclosed switchgear (hereinafter referred to as &#8220;switchgear&#8221;) is a complete set of distribution equipment for 20kV three-phase AC 50(60)Hz single busbar and single busbar sectional systems.
