The switchgear should meet the relevant requirements of the standard "AC metal enclosed switchgear", which consists of cabinet and circuit breaker. The cabinet consists of shell, electrical components (including insulation), various mechanisms, secondary terminals and wires.
Electrical components
CT for short for current transformer [such as lzbj 9- 10]
The abbreviation of voltage transformer is PT[ such as JDZJ- 10].
Grounding switch [such as JN 15- 12]
Lightning arrester (resistance-capacitance absorber) [such as HY5WS single-phase type; The sum of TBP and JBP]
Isolating switch [such as GN 19- 12, GN30- 12, GN25- 12]
High-voltage circuit breaker [e.g. oil-deficient type (S), vacuum type (Z), SF6 type (L)]
High voltage contactor [such as JCZ3- 10D/400A]
High voltage fuse [such as RN2- 12, XRNP- 12, RN 1- 12]
Transformers [such as SC(L) series dry transformers and S series oil transformers]
High voltage field display [DXN-Q type, DXN-T type]
Insulating parts [such as wall bushing, contact box, insulator, insulating heat shrinkable (cold shrinkable) sheath]
High voltage reactor [such as series type: CKSC and starter motor type: QKSG]
Load switch [e.g. FN26- 12(L), FN 16- 12(Z)]
High-voltage single-phase shunt capacitor [such as BFF 12-30- 1], etc.
Relay, watt-hour meter, ammeter, voltmeter, power meter, power factor meter, frequency meter, fuse, air switch, transfer switch, signal lamp, resistor, button, microcomputer comprehensive protection device, etc.
