Description
技术领域 technical field
本实用新型涉及一种自动转换开关。 The utility model relates to an automatic transfer switch.
背景技术 Background technique
电源切换系统类产品发展大体经历了三类：接触器类、塑壳断路器类/负荷隔离开关类、一体式自动转换开关电器类。 The development of power switching system products has generally gone through three categories: contactors, molded case circuit breakers/load isolation switches, and integrated automatic transfer switch appliances.
接触器类，此类电源切换系统以接触器为切换执行部件，切换功能用中间继电器或逻辑控制模块组成二次回路完成控制功能，一般为非标产品，缺点是主回路接触器工作需要二次回路长期通电，容易产生温升发热、触点粘结、线圈烧毁等故障，因为是非标产品，其组成元器件较多，产品质量受元器件、制造工艺制约，故障率较高，现已逐渐被新产品代替。 Contactor, this kind of power switching system uses the contactor as the switching execution part, the switching function uses the intermediate relay or the logic control module to form the secondary circuit to complete the control function, generally it is a non-standard product, the disadvantage is that the main circuit contactor needs a secondary circuit to work If the circuit is energized for a long time, it is easy to cause failures such as temperature rise, heat generation, contact bonding, and coil burnout. Because it is a non-standard product, it has many components. The product quality is restricted by components and manufacturing processes, and the failure rate is high. replaced by a new product.
塑壳断路器类，此类电源切换系统以塑壳式断路器为切换执行部件，切换功能用ATS自动控制单元完成，有机械和电气连锁，功能完善，操作性能好，使用寿命高，组成元器件较少，安装方便，该类属CB级转换开关电器，由两个断路器作为电流分断单元，并配备电流脱扣器，具备一定的保护能力，断路器的接通/分断能力比继电器高很多，该类产品稳态时由机械结构进行保持，由于断路器同负荷隔离开关本身的区别，在过电流状况下的应用效果不如PC级产品。 Molded case circuit breaker, this type of power switching system uses the molded case circuit breaker as the switching execution part, and the switching function is completed by the ATS automatic control unit, which has mechanical and electrical interlocking, complete functions, good operability, long service life, and components Less components, easy to install, this type belongs to CB level transfer switching equipment, two circuit breakers are used as current breaking unit, and equipped with current release, with a certain protection ability, the making / breaking capacity of the circuit breaker is higher than that of the relay Many, such products are maintained by the mechanical structure when they are in a steady state. Due to the difference between the circuit breaker and the load isolating switch itself, the application effect under the over-current condition is not as good as that of the PC-level product.
负荷隔离开关类，负荷隔离开关型转换开关电器是在两个负荷隔离开关的基础上加装电动操作机构、机械连锁机构、自动控制单元等一体化组装而成，电流的分断单元为负荷隔离开关，其触头灭弧系统是以分断一次电弧要求设计的，不具备电路的保护功能，这一类产品属于PC级产品，它因采用了弹簧储能、瞬时释放的加速机构，能快速接通、分断电路或进行电路的转换，产品操作性能可靠。 Load isolating switch type, load isolating switch type change-over switch is assembled on the basis of two load isolating switches with electric operating mechanism, mechanical interlocking mechanism, automatic control unit, etc., and the current breaking unit is load isolating switch , the contact arc extinguishing system is designed to break the primary arc, and does not have the protection function of the circuit. This type of product belongs to the PC level product. It can be quickly connected because of the spring energy storage and instantaneous release acceleration mechanism. , breaking the circuit or converting the circuit, the product has reliable operation performance.
一体式自动转换开关电器类，此类电源转换系统是集开关与逻辑控制于一体，无需外加控制器，真正实现机电一体化的自动转换开关，此类电源切换系统产品的触头系统采用“单刀双掷”设计，为统一设计制造，体积小，结构简单，该产品不具备电流保护功能，属于PC级转换开关电器产品。该类产品一般转换时间比较小，开关切换驱动采用电机驱动，切换平稳可靠，操作器电机驱动只在开关切换瞬间有电流通过，稳态时无需提供工作电流，节能显著，产品无温升发热、触点粘结、线圈烧毁现象，开关带有机电联锁装置，可实现自投自复、自投不自复、失压、欠压、断相保护、手动－自动转换、延时控制等，为电源切换类主流产品。 Integrated automatic transfer switch electrical appliances, this type of power conversion system is an automatic transfer switch that integrates switch and logic control, does not need an external controller, and truly realizes mechanical and electrical integration. The contact system of this type of power switching system product adopts "single pole Double-throw" design, unified design and manufacture, small size, simple structure, this product does not have current protection function, belongs to PC level switch electrical products. Generally, the conversion time of this kind of products is relatively short. The switch switching drive is driven by a motor, and the switching is stable and reliable. The motor drive of the manipulator only has current passing through the switch at the moment of switching, and there is no need to provide operating current in a steady state. The energy saving is remarkable, and the product has no temperature rise and heat Contact bonding, coil burning phenomenon, the switch is equipped with an electromechanical interlock device, which can realize automatic switching and automatic recovery, automatic switching without automatic recovery, loss of voltage, undervoltage, phase failure protection, manual-automatic conversion, delay control, etc. It is a mainstream product in the power switching category.
目前现有的自动转换开关不能进行电源的切换，使用操作不方便，结构安全性能较差。 At present, the existing automatic transfer switch cannot switch the power supply, is inconvenient to use and operate, and has poor structural safety performance.
