适用范围Application Range

GT7-12型户内交流高压隔离开关，适用于额定频率为50Hz，额定电压为12kV的户内装置。可与各种高压开关柜配套使用，尤其适用于箱型金属封闭开关柜，其可使开关柜结构简单紧凑、合理、安全可靠。分闸后建立安全可靠的绝缘间隙（明显的断口），将需要检修的线路和电气设备由隔离开关底架与电源安全隔离，以确保检修人员与设备的安全。

本产品用于固定式开关设备中，一方面可导通或隔离主回路。当操作隔离开关至分闸位置时，它可使检修的元件（如断路器等）与带电回路（如主母线等）之间分隔开来。另一方面，还可在隔离的同时接地，此时回路只可能发生对地的放电，而不会波及被检修的元件，从而确保了检修人员的安全。

gt7 - 12 series wall type indoor AC high voltage disconnector is suitable for indoor devices with rated frequency of 50 Hz and rated voltage of 12 kV. It can be used with all kinds of high voltage switchgear, especially for box type metal enclosed switchgear, which can make the structure of switchgear simple, compact, reasonable, safe and reliable. After opening, a safe and reliable insulation gap (obvious fracture) shall be established, and the lines and electrical equipment to be repaired shall be safely isolated from the power supply by the base frame of disconnector, so as to ensure the safety of maintenance personnel and equipment.

This product is used in fixed switchgear. On the one hand, it can conduct or isolate the main circuit. When the disconnector is operated to the opening position, it can separate the repaired components (such as circuit breaker, etc.) from the live circuit (such as main bus, etc.). On the other hand, it can also be isolated and grounded at the same time. At this time, the circuit can only discharge to the ground, and will not affect the repaired components, so as to ensure the safety of maintenance personnel.

产品特点Product Features

GT7-12D隔离开关总体结构简单紧凑，联锁安全可靠，隔离开关和接地开关一体化设计。接地开关具有和隔离开关相同的额定短时耐受电流和额定峰值耐受电流，接地开关关合短路电流为25kA,可以达到5次。

The overall structure of gt7-12d disconnector is simple and compact, the interlock is safe and reliable, and the disconnector and grounding switch are integrated. The grounding switch has the same rated short-time withstand current and rated peak withstand current as the disconnector. The closing short-circuit current of the grounding switch is 25kA, which can reach 5 times.
