Description
Technical field
The utility model relates to special resistance product technical field, relates in particular to a kind of test resistance case.
Background technology
Slide rheostat can change the resistance sizes that is connected into circuit, plays the effect that continuously changes size of current, but can not accurately know the resistance value that is connected into circuit.Know the resistance of the resistance that is connected into circuit if desired, will use resistance box, but existing resistance box, its measurement of factor.
Summary of the invention
The purpose of the utility model is to the deficiency of prior art a kind of test resistance case to be provided, and has the high-acruracy survey function.
For realizing above-mentioned purpose; The utility model adopts following technical scheme: a kind of test resistance case; It comprises shell, and it also comprises noninflammability epoxy resin, porcelain tube, alloy wire and support, and said alloy wire twines porcelain tube; Said noninflammability epoxy resin wraps up said alloy wire and porcelain tube, and the porcelain tube two ends are fixedly installed in said shell through support.
It also comprises snap ring, and said porcelain tube two ends are fixedly connected with support through snap ring.
Said support is fixedly installed in said shell through screw rod and nut.
Said shell is an aluminum alloy casing.
The utility model beneficial effect is: the described a kind of test resistance case of the utility model; It comprises shell, noninflammability epoxy resin, porcelain tube, alloy wire and support; Said alloy wire twines porcelain tube; Said noninflammability epoxy resin wraps up said alloy wire and porcelain tube, and the porcelain tube two ends are fixedly installed in said shell through support.Adopt the test resistance case of said structure, have high-precision measurement function.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described: as shown in Figure 1; The described a kind of test resistance case of the utility model, its structure is a kind of test resistance case; It comprises shell 1, noninflammability epoxy resin, porcelain tube 2, alloy wire and support 3; Said alloy wire twines porcelain tube 2, and said noninflammability epoxy resin wraps up said alloy wire and porcelain tube 2, and porcelain tube 2 two ends are fixedly installed in said shell 1 through support 3.Wherein, said shell 1 is an aluminum alloy casing.Further, it also comprises snap ring, and said porcelain tube 2 two ends are fixedly connected with support 3 through snap ring, makes that installation is more reliable and more stable.Further, said support is fixedly installed in said shell 1 through screw rod and nut, and dismounting and installation are all comparatively convenient.
The described a kind of test resistance case of the utility model, the test data of important parameters such as its power, voltage, electric current, frequency comes into plain view, and helps the user effectively alternating current equipments such as UPS and generator to be carried out an acceptance inspection; Its high-acruracy survey function makes measurement data more authoritative, makes the equipment control archives have more science; It has defencive functions such as fan failure detection, overvoltage, overcurrent, electric leakage; Can a plurality of parallel connections, to be suitable for the heavy-current discharge occasion.Said one of the utility model can be applied to various types of testing resistance box UPS power generators and routine maintenance and testing, engineering, inspection, factory inspection test, you can accurately test all kinds of generators and UPS equipment output power and load ability, then with the analysis software can record the entire testing process, all data changes, and automatically generate test reports, facilitate the establishment of management archiving equipment operating conditions, can be widely used in telecommunications, mobile, Unicom, electric power, aviation, banking, securities coupon, Railway Bureau, electrical services and other industries.
The above only is the preferred embodiments of the utility model, so all equivalences of doing according to the described structure of the utility model patent claim, characteristic and principle change or modify, includes in the utility model patent claim.
