The utility model adopts following scheme to realize:
A kind of power supply tester, comprise fixed mount and be connected in outside detected power supply and the inner binding post that detects between the display circuit, described detection display circuit comprises mutual inductor, wiring steel plate and the electric wire connecting junction that connects with binding post successively, electric wire connecting junction is fixed on the contactor fixed head, be connected with a load circuit on the electric wire connecting junction, load circuit connects with a display module.
As the improvement to such scheme, above-mentioned load circuit comprises the heating tube that electrically connects with detected power supply, is provided with coil transformer and solid-state voltage regulator in the load circuit, and solid-state voltage regulator is provided with eight segmentation bearing power vernier adjustment knobs.In order to be beneficial to the heating tube heat radiation, the radiator fan of cooling usefulness also is installed in fixed mount, before and after radiator fan, be provided with outlet housing and air intake cover.
As further refinement to such scheme, be respectively arranged with left shrouding, right shrouding at fixed mount left and right sides face, be provided with wicket on left shrouding, right shrouding, display module, load vernier adjustment knob are installed in the wicket of left shrouding, and binding post is installed in the wicket of right shrouding.
Simultaneously, for the ease of the lifting transportation, be provided with cover and suspension ring at the fixed mount top.Be provided with the castor of being convenient to move in the fixed mount bottom.
The utility model is reasonable in design, and testable loading range is wide, and parameter can directly be known from display module, and is easy to use; Increased its portability by suspension ring and castor are set, conveniently moving is applicable to the load testing of generator, power circuit, boats and ships and standby power supply; And have good heat sinking function, can work long hours, practicality is extremely strong.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further detailed.
Accompanying drawing 1 is the utility model embodiment decomposing state structural representation; Accompanying drawing 2 is a present embodiment assembled state structural representation.
Embodiment
For the ease of it will be appreciated by those skilled in the art that the utility model is further specified below in conjunction with embodiment and accompanying drawing.
Shown in accompanying drawing 1,2, power supply tester that present embodiment discloses comprises air compression box 1 and is connected in outside detected power supply and the inner binding post 2 that detects between the display circuit.Described detection display circuit comprises mutual inductor 31, wiring steel plate 32 and the electric wire connecting junction 33 that connects with binding post 2 successively, electric wire connecting junction 33 is fixed on the contactor fixed head 34,33 are connected with a load circuit on the electric wire connecting junction, and load circuit connects with a display module 35.This load circuit comprises the heating tube 10 that electrically connects with detected power supply, is provided with coil transformer 36 and solid-state voltage regulator 37 in the load circuit, and solid-state voltage regulator is provided with eight segmentation bearing power vernier adjustment knobs 38.The radiator fan 4 of cooling usefulness also is installed in fixed mount 1, is provided with outlet housing 51 and air intake cover 52 in radiator fan 4 front and back.The heating tube 10 that this programme adopts is for low temperature heating, by adopting high-power radiator fan 4, carries out in air compression box 1 the inside that compression makes air evenly pass electrical bar 10 each gap to air, avoids causing local heat radiation.Produce strong convection air circulation cooling electrical bar 10, entire machine can be used for a long time, even can be applicable on the factory-assembled line.
At fixed mount 1 top and left and right sides face be respectively arranged with cover plate 7, left shrouding 61, right shrouding 62, on left shrouding 61, right shrouding 62, be provided with wicket, display module, load vernier adjustment knob are installed in the wicket of left shrouding 61, and binding post 2 is installed in the wicket of right shrouding 62.
For the ease of lifting transportation and mobile, be provided with suspension ring 8 at fixed mount 1 top, be provided with castor 9 in fixed mount 1 bottom.
During startup, at first detect the external power source lead and whether connect with binding post as requested, as requested display module 35 each parameter setting are finished simultaneously.After opening load power source, opening left shrouding 61 and open fan, is to survey circulation before and after the air in the instrument, and heating tube is lowered the temperature.Then heating tube is opened, the reference signal that provides for display module according to mutual inductor, make the voltage, electric current and the frequency status that show on the display module after loading, also can the working load vernier adjustment knob solid-state voltage regulator be regulated making heating tube arrive rated voltage, thereby genset or other power supplys are tested.
During shutdown, at first heating tube is closed, keep fan in operation a period of time to the heating tube temperature lower, close fan again, stop whole tester running.
This tester can be for 0 to peaked resistive performance load and sectional type load testing, band power fine adjustment, and voltage and current, frequency, power factor (optional) and the working time of measuring each bar line.The test load range of capacity is big: 0-200W, and 0-400W, 0-500W, but also root a tree name customer demand designs.
Whole instrument is reasonable in design, and is convenient and practical, more than is the preferable implementation of the utility model, need to prove, any conspicuous replacement is all within the utility model protection domain under the prerequisite that does not break away from the present utility model design.
