Abstract

The utility model discloses a single-phase high-power nonlinear load box which comprises a box body. A moulded case breaker, a temperature controller, alternating-current contacts, a diode, an intermediate relay, a fuse, a time relay, a thermal relay and axial flow fans are arranged in the box body. The axial flow fans are arranged at the bottom of the box body, a capacitor chamber is arranged on one inner side of the box body, and a plurality of groups of first holes are reserved on the other side of the box body. The single-phase high-power nonlinear load box has an automatic overheat protection function and cannot be overheated and burnt in case that the fans do not rotate, and even if in 24-hour load, and internal components cannot be red and heated and are long in service lives. In addition, resistivity and capacitivity of a UPS (uninterrupted power supply) can be separately directly detected. The load box can be used as linear load, has the full-wave and semi-wave load conversion function, and is in modularized design and convenient to maintain.

Description

A kind of single-phase high-power nonlinear load case

Technical field

The utility model relates to the pick-up unit field of AC power, particularly relate to a kind of single-phase high-power nonlinear load case.

Background technology

When load box was check electric current, voltage transformer (VT), the various service loads that provide specially were the equipment for test rectifier, transducer, accumulator and genset AC power power.In commercial production, need to load capacity, the capacity of rectifier, transducer, accumulator and genset AC power be detected, guaranteeing the normal operation of equipment, during detection except using detector, also must survey load by the training biopsy, so that Measurement accuracy.But easily rubescent hot during load box of the prior art work, and can't directly survey separately the resistive and capacitive of UPS.

Therefore, design for above-mentioned situation and have overheated automatic protection functions, and can directly survey separately the resistive and capacitive of UPS, possess a kind of single-phase high-power nonlinear load case that function is changed in all-wave and half-wave idling, just inventor's problem to be solved.

The utility model content

The technical matters that the utility model mainly solves is to provide a kind of single-phase high-power nonlinear load case, can directly survey separately the resistive and capacitive of UPS, possesses all-wave and function is changed in half-wave idling.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of single-phase high-power nonlinear load case is provided, comprise casing, described box house is provided with breaker of plastic casing, temperature controller, A.C. contactor, diode, auxiliary reclay, fuse, the time relay, electrothermal relay and axial flow blower, described axial flow blower is arranged at the bottom of casing, described box house one side is provided with the electric capacity chamber, and the casing opposite side arranges some groups of holes one.

In preferred embodiment of the utility model, described electric capacity chamber is provided with some electrochemical capacitors, and described electrochemical capacitor is arranged on mounting base; The some band lamps of described casing outer setting locking press button, several holes two, miniature circuit breaker and temperature controller; Described mounting base is the up and down tunable arrangement, is provided with the thin louvre of some punchings on described mounting base, is provided with some U-shaped resistance on the left of described casing.

The beneficial effects of the utility model are:

1, the utlity model has overheated automatic protection functions, in the situation that blower fan does not turn, situation overheated, scaling loss can not occur yet, even loaded in continuous 24 hours, inner member is also without the red heat phenomenon, and its safe life is long;

2, the utility model can directly be surveyed separately the resistive and capacitive of UPS, also can be used as linear load and use, and possess all-wave and function is changed in half-wave idling, in addition, adopts modular design, and is easy to maintenance.
