Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is further described:
A kind of combined type up-flow case to shown in Figure 5, comprises casing like Fig. 1; Casing is a hexahedron; Casing includes framework 1, universal wheel 4 is installed below the framework 1, and framework 1 two ends are equipped with handle 8; Panel 2 is installed on the framework 1, current lifting device 5, stepup transformer 6, straight-through current transformer 7 and reometer 9 are installed in the casing; Screw base fuse 10, air switch 11, power light 12 and attaching plug 13 are installed on the panel 2 above the casing; On the panel 2 of casing side binding post 3 is installed, binding post 3 includes public binding post, no-load voltage ratio binding post and ground connection binding post; Attaching plug 13 and air switch 11, power light 12 screw base fuses 10, stepup transformer 6 successively be linked together; The extension line of stepup transformer 6 is connected to the inlead of current lifting device 5; Current lifting device 5 extension lines one end is connected to public binding post, the other end is drawn out to the no-load voltage ratio binding post through punching current transformer 7, and the secondary connection post of straight-through current transformer 7 is connected with reometer 9.
Embodiment recited above describes the preferred implementation of the utility model; Be not that design and scope to the utility model limits; Under the prerequisite that does not break away from the utility model design concept, common engineering technical personnel make the technical scheme of the utility model in this area various modification and improvement all should fall into the protection domain of the utility model; The technology contents that the utility model is asked for protection all is documented in claims.
Cabinet design in the utility model is square, the case structure that has that convenient in carrying, area occupied are little, do not need advantages such as repetition wiring between instrument.Move mode is designed to four-wheel-type, promptly at four pin of casing rotatable universal wheel is installed, and has good stability when mobile and can change the advantage of direction when mobile arbitrarily.The frame manufacture material of casing adopts the angle steel that lifting capacity is strong, physical strength is high, and panel selects for use the epoxy resin board that insulating property are strong, physical strength is high to make.Binding post adopts the copper spiral big electric current binding post that conductive capability is strong, insulation crust is arranged.
Current lifting device is positioned at the left downside of casing, adopts CARBURIZING FURNACE FOR STAINLESS FASTENER to fix; The voltage panel of stepup transformer and operating handle are embedded in the upper right corner of casing top panel; Reometer is embedded in the middle part, left side of casing top panel; Straight-through current transformer is installed in the forward right side in the casing, and fixes with rivet.Primary current binding post that the common port binding post of current lifting device, current lifting device are drawn through straight-through current transformer (no-load voltage ratio is 150/5,200/5,300/5,600/5) and ground connection binding post all are installed on the front panel, attaching plug, power light, air switch, screw base fuse are installed on the top panel again.
In the utility model; Attaching plug connects with air switch, power light, screw base fuse, stepup transformer successively; The stepup transformer extension line is connected to the inlead of current lifting device; The public binding post of current lifting device extension line one termination, the other end are drawn out to 4 no-load voltage ratio binding posts after the conversion of punching current transformer ratio, the secondary connection post of straight-through current transformer is connected with reometer simultaneously.
In the utility model, the each several part role is: casing be used for protecting the inside element, prevent by outside destroy and be convenient to move.Power light will be bright after air switch closes, and plays suggesting effect to the staff.Stepup transformer is used to change the voltage of current lifting device.Current lifting device is used for providing test to be added in the primary current of current transformer.Straight-through current transformer is used for converting primary current to secondary current, on reometer, shows again, and how many staff can be according to the primary current value that the numerical value of reometer and the no-load voltage ratio that connects are accurately extrapolated on the equipment of being added in, and is convenient to operate.Ground connection binding post and screw base fuse all shield.
The principle of work of the utility model is: after the energising; Operating handle through regulating stepup transformer changes output voltage; Thereby change the output current of current lifting device, what reometer showed is the secondary current value that the punching current transformer is drawn no-load voltage ratio that corresponding binding post identifies that connects, and converts through no-load voltage ratio; Can know how many primary currents that is added in current transformer in the through-flow test is, can accomplish through-flow test accurately, efficiently.
The use of the utility model has thoroughly changed and has become former experiment process; The situation of line need carried and repeat to instrument and equipment when avoiding testing the place difference; Shortened the test averaging time of a through-flow test of current transformer; Shorten to present 4.3 minutes by original 10.8 minutes, reduced checking time, improved work efficiency.
