经过不断的验证、改进再验证、再改进,
仿威图机柜的功能也在不断的完善,在其他领域的科技升级和创新,也不断的融入到仿威图机柜的生产技术中。那么仿威图机柜都有哪些保护功能?
After continuous verification, improvement and verification, and improvement, the function of the imitation Weitu cabinet is also constantly improved, in other fields of science and technology upgrading and innovation, but also constantly into the production technology of the imitation Weitu cabinet. So what are the security protection functions of the imitation Weichart cabinet?
低压断路器保护功能:低压断路器在电路中除起控制作用外,还具有一定的保护功能,如过负荷、短路、欠压和漏电保护等。
Low voltage circuit breaker protection function: low voltage circuit breaker in the circuit in addition to play a control role, but also has a certain protection function, such as overload, short circuit, undervoltage and leakage protection.
短路保护:由内部螺旋状导体和衔铁组成;过载过流保护:由双金属片和机械脱扣装置构成;失压保护:由失压线圈,衔铁和机械脱扣装置组成。
Short circuit protection: composed of internal spiral conductor and armature; Overload and overcurrent protection: composed of bimetal sheet and mechanical release device; Loss of pressure protection: it is composed of loss of pressure coil, armature and mechanical release device.
隔离开关保护功能
Isolation switch protection function
维护人员的人身:在电气设备检修时,提供一个电气间隔,并且是一个明显可见的断开点,用以保障维护人员的人身。
Safety of maintenance personnel: During the maintenance of electrical equipment, an electrical separation is provided and a visible disconnect point is used to ensure the personal safety of maintenance personnel.
短路保护功能:负荷开关具有在非故障条件下,接通或分断负荷电流的能力和一定的短路保护功能。
Short circuit protection function: load switch has the ability of connecting or breaking load current and certain short circuit protection function under non-fault conditions.
总线保护作用:断路器在断开位置,只能先合母线侧隔离刀闸,才能合线路侧隔离刀闸。此种接线不仅防止带负荷拉、合隔离开关,而且能防止违反开关、刀闸操作原则的违规操作。
Bus safety protection: in the open position of the circuit breaker, only the isolation switch on the bus side can be closed before the isolation switch on the line side. This kind of connection not only prevents pulling and closing the disconnecting switch with load, but also prevents illegal operation in violation of the operating principles of switch and switch.
负荷开关保护功能
Load switch protection function
一般装有简单的灭弧装置,但其结构比较简单。其工作过程是:分闸时,在分闸弹簧的作用下,主轴顺时针旋转,一方面通过曲柄滑块机构使活塞向上移动,将气体压缩;另一方面通过两套四连杆机构组成的传动系统,使主闸刀先打开,然后推动灭弧闸刀使弧触头打开,气缸中的压缩空气通过喷口吹灭电弧。
Generally equipped with a simple arc extinguishing device, but its structure is relatively simple. The picture shows a pneumatic high-pressure load switch, its working process is: when the brake, under the action of the brake spring, the main shaft rotates clockwise, on the one hand, through the crank slider mechanism to move up the piston, the gas compression; On the other hand, through the transmission system composed of two sets of four-link mechanism, make the main knife open first, and then push the arc extinguishing knife to open the arc contact, the compressed air in the cylinder through the nozzle to blow out the arc.
The security protection function of the imitation Vito cabinet is not a single component, but many components cooperate with each other. Some components have the same or similar protection effect. The combination of the two components adds a safety protection insurance. More content to this www.tongyuhengcheng.com consultation!
