Facilitate the assembly of diesel generators

What protection should diesel generators be equipped with for daily use:

1. Longitudinal differential maintenance: inter-phase short-circuit maintenance of stator windings and their exit wires.

2. Transverse differential maintenance: maintenance of short-circuit between turns of stator windings. This type of maintenance is performed only when the stator windings of one phase have two or more parallel branches forming two or three neutral outlet terminals.

3. Single-phase grounding maintenance: single-phase grounding maintenance of generator stator windings.

4, excitation circuit grounding maintenance: for the excitation circuit grounding fault maintenance.

5, low excitation, loss of magnetic maintenance: in order to avoid large generating units of low excitation (excitation current below the static stability limit of the corresponding excitation current) or lose excitation (excitation current is zero), from the system to absorb a lot of reactive power and bad influence on the system, 100MW and above capacity of generators are installed with this maintenance.

6. Overload maintenance: The maintenance of the signal when the generator runs beyond the extra load for a long time. Small and medium-sized generators are only equipped with stator overload maintenance; Large generator sets should be separated from installation stator overload and excitation group overload maintenance.

7, stator winding overcurrent maintenance: when the generator longitudinal difference maintenance scale short circuit, and short circuit component maintenance or circuit breaker rejected action, this maintenance as the backup of external short circuit, but also as the backup maintenance of longitudinal difference maintenance.

Jiangsu Meao Power Technology Co., Ltd. is an important manufacturer of diesel generators. The company mainly manufactures and sells diesel generator sets with power of 3-3000kW, mobile power station of 24-600kW, Marine emergency diesel generator set of 24-800kW, gas generator set, heavy oil generator set and all kinds of imported series, special series (trailer, static speaker, mobile lighthouse, container, etc.) diesel generator At the same time, we are engaged in generator set maintenance and after-sale service of generator set accessories.
