Description
Technical field
The utility model relates to reactive power compensator technical field, is specially a kind of highly sensitive reactive power compensator.
Background technology
Under the demand driving of national grid safety, the quality of power supply, energy-saving and emission-reduction, the development and apply of reactive power compensator is very fast, and country is vigorously advocating conservation-minded society especially at present, and wherein energy-saving and emission-reduction are important rings.Reactive power compensator belongs to electric power energy-saving product, also be the conservation measures be uniquely mentioned in power supply policy and electric power law in all electric power energy-saving products, tradition reactive power compensator MSC(mechanical switch switched capacitor) there is mechanical switch length operate time and the shortcoming of waving not, this makes it be difficult to accurately drop into Capacitor banks when point of zero voltage, very easily cause and shove, damage Capacitor banks, and easily produce electric arc when disconnecting Capacitor banks, mechanical switch contact arc discharge is caused to burn, unnecessary trouble is brought to maintenance personal, for this reason, we propose a kind of highly sensitive reactive power compensator.
Utility model content
The purpose of this utility model is to provide a kind of highly sensitive reactive power compensator, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme: a kind of highly sensitive reactive power compensator, comprise bus, lead-in circuit breaker, current transformer, inductance instrument transformer, idle compensating control, Fiber isolation and brilliant valve tube drive circuit, first brilliant valve pipe valve group, second brilliant valve pipe valve group, filter inductance and Capacitor banks, described bus is connected with three electric wires, lead-in circuit breaker is provided with between described bus and three connection wiring lines, described current transformer is all connected with three electric wires with inductance instrument transformer one end, the other end is connected with idle compensating control, described idle compensating control and Fiber isolation and brilliant valve tube drive circuit are cascaded, described first brilliant valve pipe valve group and the second brilliant valve pipe valve group are connected in parallel, and two ends are electrically connected with brilliant valve tube drive circuit and three with Fiber isolation respectively, described first brilliant valve pipe valve group and the second brilliant valve pipe valve group have all been connected a filter inductance and a Capacitor banks.
Preferably, the access point of described filter inductance and Capacitor banks is the center valve body of the first brilliant valve pipe valve group and the second brilliant valve pipe valve group.
Preferably, described first brilliant valve pipe valve group and the second brilliant valve pipe valve group are all made up of three brilliant valve pipe valves.
Compared with prior art, the beneficial effects of the utility model are: this highly sensitive reactive power compensator, thyristor valve is adopted to replace mechanical switch, operate time is fast, accurately can drop into Capacitor banks at point of zero voltage place, effective minimizing is shoved, capacitor for voltage protection group, and thyristor valve is when current over-zero, automatic disconnection Capacitor banks, there is not the problem producing electric arc, the switching cycle of Capacitor banks, namely first throw and first cut, first cut the strategy first thrown, this makes each Capacitor banks can divide the linked network time, effectively extend useful life, adopt Intelligent Control Strategy, effectively can avoid the throw in-of oscillation problem of Capacitor banks, stablizing of guarantee system.
