Abstract
The utility model discloses a load case which comprises a case body, cooling fans, axial-flow fans, alternating current contactors, wire vias, a fuse attachment and a second temperature controller. The cooling fans are disposed on the side of the case body. A lamp button, a single-phase alternating-current digital-display multifunctional instrument, a fast connector and a first temperature controller are disposed on the outer side of a front door of the case body. The alternating current contactors, the wire vias, the fuse attachment, the second temperature controller and resistors are disposed inside the case body. With the fast connector, operations are allowed from an outer door of the case body. Clear marks are provided for power of each group of loads, and voltage, current, power, inner temperature of the case and the like can be detected for each group. In addition, the loads have the function of automatic overheat protection, burnt by overheating is avoided even when the fans stop, continuous 24-hour loading of the loads is guaranteed, internal components are avoided being red and hot, and the safety lifetime of the load case is prolonged. The load case is modularly designed and is convenient to maintain.
Description
Technical field
The utility model relates to the proving installation field of power-supply device, particularly relate to a kind of load box.
Background technology
At present; be used for the load box of UPS performance test or burn-in test in the process of test; complicated operation usually; and the power for every group of test does not all have clear and definite sign, can not detect the parameters such as voltage, electric current, power, box house bulk temperature of every group, and; after loading on around-the clock loading running; inner member usually the red heat phenomenon can occur, and load usually can because not having the overheated scaling loss of overheated automatic protection functions, make the safe life of whole load box very short.
Therefore, design for above-mentioned situation and can identify every group of measured power, have overheated automatic protection functions, modular design, a kind of load box easy to maintenance, inventor's problem to be solved just.
The utility model content
The technical matters that the utility model mainly solves is to provide a kind of load box, can identify every group of measured power, has overheated automatic protection functions, and modular design is easy to maintenance.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of load box is provided, comprise casing, radiator fan, axial flow blower, A.C. contactor, cable-through hole, the attached seat of fuse and temperature controller two, described radiator fan is arranged at the side of casing, described casing main entrance outer setting has band button, single-phase AC Multi-functional digital display instrument, rapid-acting coupling and temperature controller one, and described box house is provided with A.C. contactor, cable-through hole, the attached seat of fuse, temperature controller two and resistance.
In preferred embodiment of the utility model, described casing top is provided with wire hood, and the bottom is welded with angle steel, and the bottom is provided with two axial flow blowers; Described outer capping plate is screwed, and the steel plate position of described internal layer fixed resistance can be regulated front and back; Described resistance is straight type electric resistance of stainless.
The beneficial effects of the utility model are:
1, the utility model not only can be tested three-phase UPS but also can test single-phase UPS, what test port was selected is rapid-acting coupling, need not open just direct door operation outside casing of box cabinet door, and load has clear and definite sign for the power of every group of test, and can detect voltage, electric current, the power of every group, the parameters such as box house bulk temperature;
2, in addition; load has overheated automatic protection functions; in the situation that blower fan does not turn; situation overheated, scaling loss can not occur yet; guaranteed that load loaded in continuous 24 hours, inner member the red heat phenomenon can not occur yet, has extended the safe life of load box; complete machine adopts modular design, and is easy to maintenance.
