Abstract
The utility model relates to an exclusively used tool used for the maintenance engineering of electrical tests, which is a contact measuring device used for measuring DC resistance among armature rectifying plates of a DC motor. The utility model is composed of an upper and a lower semicircular supporting brackets, bearing rolling wheels, an insulating plate, an electrode probe, an operating rod, a spring, etc. The device has simple structure, easy manufacture and convenient use. Data measured by the device when electrical test people of a power generating plant check and measure the DC resistance among the armature rectifying plates of the DC motor in the maintenance of a power generator is accurate. The surface of a measured rotor is not damaged in the process of measurement. Work efficiency can be increased and worker's labor intensity can be reduced.
Description
The utility model belongs to the specific purpose tool in the electrical test maintenance engineering, is used to measure the contact measurement device of the direct current resistance between direct current generator armature rectiblock.
The electrical test personnel of generating plant are in to generator overhaul each time, need carry out the direct current resistance test of its auxiliary device excitation system between interior DC motor rotor armature rectiblock, purpose is to check whether the welding situation at welding between each winding of armature and rectiblock and other positions is good; Have or not short circuit between rectiblock.Way of the prior art is the measuring lead wire termination C with double bridge QJ-44 or digital instrument for measuring DC resistance

2With rectiblock, could measure direct current resistance, and this method seems simply, operation is but quite required great effort.Be close to the endurance that needs the people on the one hand and consume great muscle power and keep, and because resistance has much relations with the degree of being close to, the measurement of each resistance all needs constant endurance of regular hour to keep, if operating personnel firmly have when inhomogeneous slightly, the data of being surveyed just not necessarily meet the requirements, and need resurvey; Firmly excessive on the other hand, metal tip is stung bad rectiblock, forms pit, strikes sparks easily during operation, forms hidden danger, and is dangerous, also reduced life cycle.In a word, this manual contact measuring method has labour intensity big, inefficiency, shortcoming such as measurement data is inaccurate.
The purpose of this utility model is to avoid above-mentioned weak point of the prior art, and a kind of simple and easy specific purpose tool is provided---measure the device of direct current resistance between the armature rectiblock, improve power plant electricity testing crew work and efficient the during direct current resistance between check measurement direct current generator armature rectiblock in each maintenance, alleviate labor strength generator.
The purpose of this utility model can reach by following measure: the device of direct current resistance between this measurement armature rectiblock as shown in Figure 1, by up and down two semicircle bearing supports, insulcrete, electrode catheter and operating rods, spring etc. are formed, it is characterized in that lower supporting frame 2 and 1 usefulness bolt connect into a circle body on two semicircles, equally distributed at least three supporting rollerns 3 are housed in the circle abut against the rotor outer rolling of surveying.Be fixed with upper insulation plate 6 in the centre position of upper support frame 2, operating rod 9 is made thru-bolt shape, and the handstand shape passes lower insulation plate 5 from the bottom up and pressure spring 12 is ganged up with upper insulation plate 6 and upper support frame 2, is integral with register pin 11 cards.Four electrode catheter 7 symmetries are inserted in the insulcrete both sides, and upper insulation plate 6 is passed on top, and the lower end is fixed on the lower insulation plate 5.
The drawing of accompanying drawing is described as follows:
Fig. 1 looks synoptic diagram for the device master who measures direct current resistance between the armature rectiblock.
Fig. 2 is for measuring the device schematic top plan view of direct current resistance between the armature rectiblock.
Among Fig. 1: 1-lower supporting frame, 2-upper support frame, 3-supporting rollern, 4-supporting rollern frame, 5-lower insulation plate, 6-upper insulation plate, 7-electrode catheter, 8-operating rod bearing, 9-operating rod, 10-handle, 11-register pin, 12-pressure spring.
Among Fig. 2: 2-upper support frame, 6-upper insulation plate, 7-electrode catheter, 8-operating rod bearing, 9-operating rod, 13-insulcrete gib screw, the last lower supporting frame coupling bolt of 14-.
The utility model is done a step below in conjunction with accompanying drawing embodiment and is described in detail:
As shown in Figure 1, this measures the device of armature rectiblock direct current resistance, and lower supporting frame 2 and 1 can be made by iron, aluminium, casting in bronze on it, also can by mould firmly, the nylon manufacturing, also can be welded, but be processed into concentric garden after two semicircle bearing supports must tighten together up and down by steel plate.Its internal diameter is determined that by the survey root diameter general internal diameter equals the root diameter of surveying and adds two supporting rollern diameters.Supporting rollern support and operating rod bearing can with the bearing support integrally casting, also can the fixing or welding in back.The structure of supporting rollern 3 can be interior hard outer soft, and interior axle can be by metal or moulded firmly and make, and overcoat is manufactured by resilient nylon, rubber and plastic.Help being close to rotor outer surface so on the one hand because of roller surface is flexible, guarantee to measure accurately, avoid abrading rotor surface on the other hand.Upper insulation plate 6 is attached to the internal diameter centre position of upper support frame 2, by screw retention.Operating rod 9 is bolts of similar handstand, after the appropriate location, top has through hole to do fully to install, plugs in register pin and uses; The end also has a through hole, is to insert handle pin to use.Electrode catheter 7 is generally manufactured with copper rod.Divide two groups of four electrode catheters 7 that connect lead to inject from top to bottom in four holes of insulcrete 6 and 5, positioning and fixing is on lower insulation plate 5 after same length tip is stretched out in the bottom of lower insulation plate 5.Operating rod bearing 8 has upper and lower two anchor points, and the register pin 11 when not working on the operating rod 9 is stuck in the last anchor point of operating rod bearing 8, electrode catheter retracted state.When the register pin of the detection limit operating rod 9 following anchor point at operating rod bearing 8, the electrode catheter contact rotor that is fixed on the lower insulation plate 5 can be measured.
The utility model has following advantage compared to existing technology:
1, uses this device gained measurement data accurate, in measurement, do not damage measured turning to The surface of son.
2, utilize this device to detect, can improve workman's work efficiency, alleviate labor strength.
3 apparatus structures are simple, easy to manufacture, easy to use.
