Abstract
The utility model relates to a compensation device of an oil field power distribution system. The compensation device is arranged on the column with the power distribution and the automatic reactive power compensation as a whole. The technical problem solved is that the operating situation of the reactive power compensation condenser can not visually know and transfer according to the change of the load. The utility model is characterized in that: the three circuits through the inner of the case are separately connected with a contact of an AC contactor, a reactor and a capacitor in the case; the circuits (B, C) are connected with a dual-way controlling thyristor and the AC contactor, the secondary port of the transformer is connected with the rectification and voltage regulation module by the circuit through the current transformer. The problem of compensating in time and reactive power transferring reversely is solved. The utility model has the advantages that the operation status of the electrical capacitor can be known directly, the compensation condenser can automatically transfer according to the load, the loss is reduced greatly, and the operation time rate is improved.
Description
Technical field
The utility model relates to the used compensation arrangement of a kind of oil-field power system, belongs on a kind of post the collection distribution to be installed and imaginary power automatic compensation is the compensation arrangement of one.
Background technology
The distribution system in oil field is distributed in the wilderness mostly in the oil field at present, multi-point and wide-ranging, the management very difficult, and motor to be tie mostly with the lead reduce to common voltage by step-down transformer with high pressure uses, so electric power exists loss on transmission, line loss problem in course of conveying, operating cost is higher.Though the power factor compensation device of already used distribution transformer platform can solve the problem that motor operate power factor is low, the electric network reactive-load loss is big, but because compensation arrangement has generally adopted the mode of attached power capacitor compensation case outside the transformer platform distribution box, existing problems are: because the compensates electric capacitor is in the housing of independent sealing, the operation conditions of power capacitor can't intuitively be understood, and can not in time find and recover in the time of can't normally moving when power capacitor breaks down.The 2nd, during oil pumper work out of service, capacitor still moves on electrical network, causes to send idlely, makes the distribution system power factor leading, has increased grid loss on the contrary.
The utility model content
Technical problem to be solved in the utility model is: the problem of switching can't intuitively be understood and can not be carried out with load variations to the reactive-load compensation capacitor operation conditions.
Technical solution adopted in the utility model: this compensation arrangement constitutes on three line tower foundations, and three circuits that pass in the housing connect housing interior ac contactor contact, reactor and capacitor respectively; Its two circuits connect bidirectional triode thyristors and A.C. contactor, and the single line road is passed current transformer the instrument transformer secondary port is connect rectification and Voltage stabilizing module, wherein at the resistance of Voltage stabilizing module both sides shunt capacitor and series connection.
The advantage that the utility model had:, make that capacitor was out of service, has solved timely compensation and has sent idle problem when motor was stopped transport because this compensation arrangement has rectification and Voltage stabilizing module.According to actual needs simultaneously, can be provided with indicator light on compensation circuit, can intuitively understand the operation conditions of power capacitor, compensation condenser can carry out automatic switching with load, and loss reduces greatly, rate when improving operation, and social benefit and economic benefit are obvious.
