断路器和漏电保护器有什么区别?

来源:http://www.jntongyu.com/ 日期:2022-04-06 发布人:tongjid

  断路器是配电系统中主要的保护电器之一,其主要作用是作为短路、过载、接地故障、失压以及欠电压保护,但是很多人分不清它和漏电保护器有什么不一样,下面我们就来讲讲吧。
  Circuit breaker is one of the main protection appliances in the distribution system, its main role is as a short circuit, overload, grounding fault, loss of voltage and under voltage protection, but many people can not distinguish it and leakage protector what is not the same, let's talk about it.
  微型断路器由操作组织、触点、维护设备(各种脱扣器)、灭弧体系等构成。其主触点是靠手动操作或电动合闸的。主触点闭合后,悠闲脱扣组织将主触点锁在合闸方位上。过电流脱扣器的线圈和热脱扣器的热元件与主电路串联,欠电压脱扣器的线圈和电源并联。
  The MCB consists of operation organization, contacts, maintenance equipment (various tripping device), arc extinguishing system, etc. The main contact is manually operated or electrically closed. After the main contact is closed, the leisure tripping organization locks the main contact on the closing direction. The coil of the overcurrent release and the thermal element of the thermal release are connected in series with the main circuit, and the coil of the undervoltage release is connected in parallel with the power supply.
  当电路发作短路或严峻过载时,过电流脱扣器的衔铁吸合,使悠闲脱扣组织动作,主触点断开主电路。当电路过载时,热脱扣器的热元件发热使双金属片上曲折,推进悠闲脱扣组织动作。当电路欠电压时,欠电压脱扣器的衔铁开释。也使悠闲脱扣组织动作。
  When the circuit is short-circuited or severely overloaded, the armature of overcurrent tripping device is closed, so that the loose tripping organization acts, and the main contact disconnects the main circuit. When the circuit is overloaded, the heat element of the thermal release device heats up and twists on the bimetal sheet, promoting the leisurely release organization action. When the circuit is undervoltage, the armature of undervoltage release. Also allows for leisurely tripping to organize movements.
  断路器的功能相当于熔断器式开关与过欠热继电器等的组合。漏电保护器则具有过载和短路保护功能,可用来保护线路或电动机的过载和短路,亦可在正常情况下作为线路的不频繁转换启动之用。
  The function of the circuit breaker is equivalent to the combination of fuse switch and overheat relay. Leakage protector has overload and short circuit protection function, which can be used to protect the overload and short circuit of the line or the motor, and can also be used as the infrequent conversion of the line under normal circumstances.
  低压断路器的功能相当于闸刀开关、过电流继电器、失压继电器、热继电器及漏电保护器等电器部分或全部的功能总和,是低压配电网中一种重要的保护电器。
  The function of low-voltage circuit breaker is equivalent to knife switch, over-current relay, voltage loss relay, thermal relay and leakage protector and other electrical parts or all the functions of the sum, is an important protection of low-voltage distribution network.
  漏电保护器有对漏电流检测和判断的功能,而不具有切断和接通主回路功能,这一点跟低压断路器不一样。另外,ABB微型断路器价格不会很一样,受市场以及需求量的影响而变化。
  Leakage protector has the function of leakage current detection and judgment, and does not have the function of cutting off and connecting the main circuit, which is different from the low-voltage circuit breaker. In addition, ABB MCB prices will vary depending on the market and demand.
  如果在不同场所中,出现间接触电问题,给人体造成损伤是不一样的,因此需要按照场所的实际情况来选择相应的断路器产品。针对比较容易出现漏电问题的场所,应挑选比较灵敏的产品,相比干燥空间,潮湿空间更容易出现触电问题,因此要选择安装电流合适的机器。
  If in different places, indirect electric shock problem, damage to the human body is not the same, so need to choose the corresponding circuit breaker products according to the actual situation of the place. For places prone to leakage problems, sensitive products should be selected. Compared with dry space, electric shock is more likely to occur in wet space, so it is necessary to choose a machine with appropriate current.
  总之,通过以上的讲解,我们不仅知道了微型断路器是什么,还知道了它和漏电保护器的区别,所以如果您还有地方不明白的话,可以来我们网站www.jntongyu.com进行咨询。
  In short, through the above explanation, we not only know what the micro circuit breaker is, but also know the difference between it and the leakage protector, so if you still have a place do not understand, you can come to our website www.jntongyu.com for consultation.
