Description
Technical field
The utility model relates to a kind of device that diesel generator set is carried out load test.
Background technology
Original load experimental provision is to adopt water resistance to load, and water resistance is made up of battery lead plate a big pond, water, electrolyte and several; Battery lead plate inserts in the water of conduction, forms water resistance at battery lead plate; The size of water resistance is relevant with the contact area of battery lead plate and water, and the small resistor value is more little more for contact area, and the big more resistance value of contact area is big more.On original load experimental provision structure its drawback is arranged: battery lead plate is as easy as rolling off a log being corroded in water; Produce a large amount of heats during the battery lead plate energising and make water vapor; Because water resistance and some corrosive gass; Cable on plate corrosion of damp and hot and acrid environment meeting accelerating electrode and the battery lead plate is aging, whenever just needs replacing battery lead plate and cable after a while.The size of load is to control through the degree of depth that servomotor is regulated in the battery lead plate insertion water, and the stroke of motor is not easy accurate control, needs to regulate repeatedly just can obtain needed load value, causes test efficiency lower like this.
Summary of the invention
The purpose of the utility model is the defective that overcomes prior art, provides a kind of diesel generator set novel load test apparatus.Original diesel generator set load experimental provision be prone to be corroded, to load control out of true, problem that test efficiency is not high have been solved.
The purpose of the utility model is achieved in that
The novel load experimental provision of the described diesel generator set of the utility model; Comprise breaker cabinet, contactor cabinet, load cabinet and control desk; It is characterized in that described breaker cabinet is made up of the cabinet of breaker cabinet and the isolating switch that is fixedly mounted on the cabinet the inside of breaker cabinet; The isolating switch lower end connects diesel generator set with the breaker cabinet output cable, and the isolating switch upper end is connected on the bus row of described contactor cabinet with the breaker cabinet output cable; The contactor cabinet is made up of the cabinet of contactor cabinet, bus row and the contactor that is fixedly mounted in the cabinet of contactor cabinet, and the contactor leading-out terminal is connected on the inlet wire load copper bar of said load cabinet with the contactor output cable; Said load cabinet is made up of electrothermal tube, load cabinet frame work, load copper bar, insulator and Industrial fan, and the electrothermal tube two ends are fixed on the load copper bar, connects with insulator between load copper bar and the load cabinet frame work, and the load copper bar extends outside the load cabinet frame work; Said control desk is made up of framework, control desk panel, the computing machine and the genset dedicated tester that are installed on the control desk panel, and control desk is connected with the contactor cabinet through control signal wire.
The purpose of the utility model also can realize through following technical scheme, the novel load experimental provision of described diesel generator set, and its characteristics are that electrothermal tube has the stainless steel radiating fin.
Crucial part in the utility model structure adopts computer intelligence control to drop into payload, adopts air-cooled electrothermal tube as test load.Practicality place of the utility model is that computer intelligence control drops into payload and makes load test apparatus more intelligence, degree of accuracy are higher, and has improved efficient; The cable that is connected with load is corrosion-vulnerable not, and is durable.Original diesel generator set load experimental provision be prone to be corroded, to load control out of true, problem that test efficiency is not high have been solved.
In the utility model, electrothermal tube is the tubular metal structure, has the stainless steel radiating fin; Heat is dispersed in the air through radiating fin; Two Industrial fans that the load cabinet has blow away the heat in the load cabinet, make electrothermal tube be forced cooling, and so dual radiating effect is better; The load copper bar of load cabinet extends to outside the load cabinet, and cable is connected on the load copper bar, and cable is in the Industrial fan inlet side, and the heat of load generating can not influence cable like this, thereby obtains the serviceable life of cable prolonging.The control of genset load is accomplished through computing machine; Computing machine and genset dedicated tester have been installed the special test software supporting with the genset dedicated tester through the RS232 serial communication on the operating system, input needs the load value of loading on software; The genset tester is exported signal automatically; Signal is transferred on the contactor through the control line of control desk and contactor cabinet, makes contactor closed, thereby real load drops into; The whole control process intelligentization, simple to operation.
Compare with original diesel generator set load experimental provision and the utlity model has following advantage: 1, load good heat dissipation effect, cable is difficult for aging; 2, load control is intelligent, easy to operate, and efficient is high.
