配电环节中必不可少的设备是断路器

来源:http://www.jntongyu.com/ 日期:2022-05-06 发布人:tongjid

  电路安装过程中,需要配置不少设施,断路器就是一种,那断路器是什么东西呢?使用时又要注意什么呢?下面就来简单了解一番吧。
  Circuit installation process, need to configure a lot of facilities, circuit breaker is a kind of, that circuit breaker is what? What should we pay attention to when using it? Here's a brief look.
  断路器就是用来断开电路的器械装置,它主要是作用于电力输送和使用中,在配电环节中必不可少,能避免电压荷载过大导致的电路损坏、用电设备损坏等等问题。一旦电流过大,或者出现短路、欠压等故障时就会自动切断电路来保障安全。
  Circuit breaker is used to disconnect the circuit device, it is mainly used in power transmission and use, essential in the distribution link, can avoid voltage load caused by excessive circuit damage, electrical equipment damage and so on. Once the current is too large, or short circuit, undervoltage and other faults will automatically cut off the circuit to ensure safety.
  要注意选择合适的断路器。断路器本身的型号参数不少,在安装时要搭配好才行,可以根据电压、电流和用电设备来选择,否则选小了,会出现没到额定电流就跳闸,频繁跳闸会影响到正常使用,选大了就会出现超过负荷也不跳闸,导致电路烧损或用电设备损坏,可以搭配1.25倍额定电流的断路器。
  Care should be taken to select a suitable circuit breaker. Model parameters of the circuit breaker itself, when installation should match well, can choose according to the voltage, current and power equipment, or choose the small, there will be no trip to the rated current, frequent trip will affect the normal use, choose the big trip, there will be more than load circuit loss or damage to the electrical equipment, Can be used with circuit breakers of 1.25 times rated current.
  注意安装环境。断路器虽然使用广泛,但是对于周围空气温度、大气条件和污染等级都是有要求的。不能安装在温度超过40度、低于零下5度的环境,而且周围空气温差不能过大,要是一天以内温差超过30度的话,就无法使用。
  Pay attention to the installation environment. Although circuit breakers are widely used, they are required for ambient air temperature, atmospheric conditions and pollution levels. It should not be installed in an environment where the temperature is more than 40 degrees Celsius and less than minus 5 degrees Celsius, and the temperature difference in the surrounding air should not be too large. If the temperature difference exceeds 30 degrees Celsius within a day, it cannot be used.
  断路器也不能安装在气压过低的区域,譬如说海拔超过2000米的位置就无法使用。同时对于湿度也有一定的要求,湿度在40%-50%为宜,不要超过90%,或者不要低于25%。断路器不能安装在污染太高的区域,在3级以内都可以使用。
  The circuit breaker should not be installed in areas where the air pressure is too low, such as over 2000 meters above sea level. At the same time, there are certain requirements for humidity, humidity in 40%-50% is appropriate, not more than 90%, or not less than 25%. Circuit breakers should not be installed in areas that are too polluted. They can be used up to level 3.
  ABB塑壳断路器代理人员提醒大家还要注意安装要平稳。断路器很多部位是塑料材质的,很容易出现脱扣情况,会影响到使用,一定要平稳安装才行。
  ABB molded case circuit breaker agent to remind you to pay attention to the installation of smooth. Many parts of the circuit breaker are made of plastic. It is easy to trip, which will affect the use. It must be installed smoothly.
