Background technology
in petroleum drilling is produced, drill crew needs generator to provide electric energy, drives the various electrical equipments produced and in life, generator in use there will be various fault, part fault must be returned factory and could repair, and in addition, generator big or middle is repaiied and also must be returned factory and carry out.These return the generator of repair in shop reason, must test, measure various output parameter after repairing, traditional generator-motor test testing device, must assemble an intact diesel engine to drive generator.This traditional generator-motor testing device exists that noise is large, environmental pollution problem greatly, not environmentally, and meanwhile, the startup of diesel engine is pretty troublesome, particularly winter, the more difficult startup of diesel engine.
Summary of the invention
the utility model provides a kind of generator-motor testing device, overcomes the deficiency of above-mentioned prior art, it effectively can solve traditional generator-motor testing device and has that noise is large, environmental pollution greatly, not environmentally, the troublesome problem of diesel engine starting in winter.
the technical solution of the utility model is realized by following measures: a kind of generator-motor testing device, comprise frequency converter, motor, shaft coupling and generator, be electrically connected by cable between the signal output part of frequency converter and the signal input part of motor, the transmission output shaft of motor and the connector of shaft coupling one end are fixedly installed togather, and the transmission input shaft of generator and the connector of the shaft coupling other end are fixedly installed togather.
here is the further optimization and/or improvements to above-mentioned utility model technical scheme:
above-mentioned frequency converter, motor and generator are fixedly mounted in skid.
the utility model reasonable and compact in structure, quick and easy for installation, realize generator test run electrification, start easily, reduce labour intensity, reduce noise, decrease environmental pollution, improve working environment, really accomplish that production environmental protection, noise are little, no pollution, throughout the year can work well, be desirable generator testing device, make generator trial run work efficiently more convenient, be specially adapted to the generator test run test unit used during petroleum drilling is produced.
Embodiment
the utility model by the restriction of following embodiment, can not determine concrete embodiment according to the technical solution of the utility model and actual conditions.
in the utility model, for convenience of description, the description of the relative position relation of each parts is all be described according to the Butut mode of Figure of description 1, as: the position relationship of upper and lower, left and right etc. determines according to the Butut direction of Figure of description.
below in conjunction with embodiment and accompanying drawing, the utility model is further described:
as shown in Figure 1, this generator-motor testing device comprises frequency converter 1, motor 2, shaft coupling 4 and generator 5, be electrically connected by cable 3 between the signal output part of frequency converter 1 and the signal input part of motor 2, the transmission output shaft of motor 2 and the connector of shaft coupling 4 one end are fixedly installed togather, and the transmission input shaft of generator 5 and the connector of shaft coupling 4 other end are fixedly installed togather.The utility model motor 2 replaces Diesel Driven generator, controlled by frequency converter 1 by electric energy, carry out drive motor 2 through cable 3, motor 2 is connected with generator 5 by shaft coupling 4, and then driving generator 5, the rotating speed of motor 2 is consistent with generator 5 rotating speed, because motor 2 is controlled by frequency converter 1, if due to various factors impact, rotating speed and the rated speed of generator 5 are variant, known by electromotor velocity computing formula n=60f/p, the output speed of motor 2 can be changed by the output frequency size of adjustment frequency converter 1 in frequency converter 1 allowed band, the output speed of motor 2 is made to reach the rated speed of generator 5 completely, measure the various output parameters of generator 5, meet the requirement of test, really reach the object of generator 5 test run, quick and easy for installation, realize generator 5 test run electrification, start easily, reduce labour intensity, reduce noise, decrease environmental pollution, improve working environment, really accomplish production environmental protection, noise is little, no pollution, it is desirable generator testing device, throughout the year can the device of work well.
according to actual needs, above-mentioned generator-motor testing device can be made further optimization and/or improvements:
as shown in Figure 1, frequency converter 1 and motor 2 are fixedly mounted in skid.Frequency converter 1, motor 2 and generator 5 are fixedly mounted in skid, more convenient to install and transport, especially when the generator 5 used for drill crew is tested after repairing, can as required roping to on-the-spot, interim installation is not needed yet, only need to connect device power supply (DPS), then the connector of the transmission input shaft of generator 5 and shaft coupling 4 is fixed together, make generator trial run work efficiently more convenient, be specially adapted to the generator test run test unit used during petroleum drilling is produced.
the utility model is quick and easy for installation, realize generator 5 test run electrification, start easily, reduce labour intensity, reduce noise, decrease environmental pollution, improve working environment, really accomplish that production environmental protection, noise are little, no pollution, throughout the year can work well, be desirable generator 5 testing device, make generator 5 trial run work efficiently more convenient, be specially adapted to the generator test run test unit used during petroleum drilling is produced.
above technical characteristic constitutes most preferred embodiment of the present utility model, and it has stronger adaptability and best implementation result, can increase and decrease non-essential technical characteristic according to actual needs, meet the demand of different situations.
