Abstract
The utility model discloses a low-power diesel generating set control system of which the power is lower than 50 KW. The diesel generating set control system takes a general-purpose relay as a timer, and employs a two-point adjustment mode, namely, two parameters are adjusted just by setting a parameter a at a start-up time delay and setting a parameter b at a stopping time delay. The novel diesel generating set control system has the advantages of simple and convenient operation, stable and reliable control performance, convenient maintenance, time-saving, money-saving, and lower cost 50%-70% lower than the cost of the conventional product. Meanwhile, the novel diesel generating set control system uses a voltmeter and an ammeter to detect a three-phase voltage and a three-phase current respectively via a change-over switch, not only satisfying detection requirements, but also saving space, and satisfying the requirements for compact structure and beauty.
Description
Technical field:
The present invention relates to a kind of diesel-generator set control system.
Background technology:
Diesel generating set is a kind of small power generation equipment, and it is to be that fuel is the dynamic power machine that prime mover drives generator for electricity generation with the diesel engine with diesel oil etc.A whole set of unit generally is made up of with parts such as accumulator jar, protective device, emergent cabinets diesel engine, generator, control cabinet, fuel tank, starting and control.The operation principle of diesel generating set is the Diesel Driven generator operation, is electric energy with the Conversion of energy of diesel oil.In diesel engine cylinder, fully mix with the high-pressure atomization diesel oil that oil atomizer ejects through the pure air after the air filter filtration, extruding lower volume at piston stroking upward is dwindled, temperature raises rapidly and reaches the burning-point of diesel oil, diesel oil is lighted, and mist acutely burns, and volume expands rapidly, promote descent of piston, be called " acting ".Each cylinder is acting successively in certain sequence, and the thrust that acts on the piston has become the strength that promotes the bent axle rotation through connecting rod, thereby drives crankshaft rotating.With the coaxial installation of generator and crankshaft of diesel engine, just can utilize the rotation of diesel engine to drive the rotor of generator, utilize " electromagnetic induction " principle, generator will be exported induced electromotive force, just can produce electric current through the load circuit of closure.Diesel generating set can produce the noise of 95~110db usually when operation, the noise of unit operation will cause serious harm to surrounding environment.
The control module kind of diesel generating set is much mostly gathered into modularization, performance is yet stable, subject matter is exactly that price is too high, for powerful generating set, the normal at last ratio of the control module of several thousand yuan of prices, but for low power generating set, whole unit itself is with regard to several thousand yuan price, and it is irrational adopting the diesel-generator set control module on the market.Its control performance also requires same convenience and hommization though power ratio is less.My company develops this new control system for head it off.
Summary of the invention:
The purpose of this invention is to provide a kind of novel diesel gen-set control system, this system cost is low, simple to operation, control performance is stable and reliable for performance, compact conformation is attractive in appearance.
Above-mentioned purpose realizes by following technical scheme:
Adopt general-purpose relay as timer, simple to operate need not the professional debugging; Modular controller on the market adopts parametrization setting and liquid crystal display interface more, must be by being subjected to training or professional to be provided with and to regulate parameter; And the novel diesel generator fine horse control system of our company's exploitation adopts 2 adjustings; be that the unit user of service only need start time-delay to a; b shuts down two parameters of time-delay and adjusts, and the time-delay of native system control adopts is time-delay relay, adjusts simple and conveniently must the professional not operate.Because the cancellation integrated circuit (IC) chip, production cost is low; Production cost has reduced by 50% to 70% than existing product, and its price drops to four or five hundred yuan by two or three of existing product in unit, has reduced the production cost of the small-power unit of low price, strengthens its market competitiveness.Easy to maintenance, maintenance cost is low; Modular controller on the market adopts parametrization setting and liquid crystal display interface more, must be by being subjected to training or professional to be provided with and to regulate each operation parameter, have only backspace to come producer to go to keep in repair or provide new product to change by producer when module breaks down, not only spended time is long and price is very high for this; And the novel diesel generator fine horse control system employing of our company's exploitation is time-delay relay, on market, buy the replacement device easily, so long as there is a personnel of electrician's knowledge to keep in repair voluntarily, need not the professional keeping in repair does not more need anti-repair in shop reason, easy to maintenance.
By two change over switches, a corresponding voltmeter and an ammeter detect three-phase voltage and three-phase current respectively simultaneously, promptly satisfy and detect requirement, also save the space, and compact conformation satisfies requirement attractive in appearance.
