motor-operated appliance: appliance incorporating motors but without any heating elementNote 1 to entry: Magnetically driven appliances are considered to be motor-operated appliances. Household electrical appliances usually use heating elements or motors to complete their designed functions. The main functions are heating, such as heating food or air, and rotation or mechanical movement of products, such…
heating appliance: appliance incorporating heating elements but without any motor. Before introducing this definition, we need to briefly introduce the electric heating elements commonly used in household electrical appliances. PTC heating element: PTC (Positive Temperature Coefficient) heating elements are widely used for various heating applications because of their self-regulating properties and safety features. Here are…
built-in appliance: fixed appliance intended to be installed in a cabinet, in a prepared recess in a wall or in a similar location. Here, because the appliance must be installed in a reserved position (usually a cubic space with only one side open), it is a fixed installation and can be regarded as a fixed…
fixed appliance: appliance that is intended to be used while fastened to a support or while secured in a specific location. The definition emphasizes fastening to a bracket or fixing in a specific position. Generally, we think that this kind of fixation requires some installation actions and some fixing devices, these devices can be fixed…
stationary appliance: fixed appliance or an appliance which is not a portable appliance. Stationary appliance includes fixed appliance and not a portable appliance. The characteristic of a stationary appliance is that once it is put into use, it will be placed in a fixed position. At the same time, the position of the appliances will…
hand-held appliance: portable appliance intended to held in the hand during normal use. Hair dryers, electric irons, hand-held vacuum cleaners, etc. are typical examples of hand-held appliances.
portable appliance: appliance that is intended to be moved while in operation or an appliance, other than a fixed appliance, having a mass less than 18 kg. This item is relatively easy to understand. Products that are less than 18kg are relatively light, so they are easy to move during operation, including humidifiers, fans, air…
protective extra-low voltage circuit: earthed circuit operating at safety extra-low voltage which is separated from other circuits by basic insulation and protective screening, double insulation or reinforced insulationNOTE 1 Protective screening is the separation of circuits from live parts by means of an earthed screen.NOTE 2 A protective extra-low voltage circuit is also known as…
安全絶縁変圧器:安全超低電圧で機器または回路に供給することを目的とした、少なくとも二重絶縁または強化絶縁と同等の絶縁によって入力巻線が出力巻線から電気的に分離された変圧器 ここで言う変圧器は、機器や回路に電力を供給するために使用されます。最も一般的な変圧器は回路に電力を供給し、いくつかの変圧器は電化製品に電力を供給します。ここで重要となるのは入力巻線と出力巻線の絶縁対策であり、二重絶縁もしくは強化絶縁タイプ、または同等の絶縁が必要となります。この要件は、一次巻線と二次巻線が十分な絶縁を有することを保証することです。絶縁が十分であれば、変圧器の一次巻線と二次巻線間の絶縁は比較的安全です。二重の保護予防策。 スイッチの電源基板に使用される最初の種類のトランス。このタイプの変圧器は、同じ磁気コア上に一次巻線と二次巻線を重ね合わせます。したがって、一次側と二次側の間の沿面距離と電気的空間を確保するために、巻線を上下の端面に配置することはできません。以下の図に示すように、巻線は上下の端面から一定の距離にある必要があります。 安全絶縁トランスの全体図 安全絶縁トランスの全体図 The other is a drawer-type linear transformer, as shown below:
