Description

Uppfinnare: G Akerblom Provning av startmotorn d en bil kan ske genom att hryta fOrbindelsen Indian bane-net och startmotorn samt mellan dessa inkoppla en matapparat med en amperemeter, eventuellt aven en voltmeter. Matapparaten har en shunt f6r huvudstrommen fran batteriet till startmotorn; shunten är dimensionerad for de stoma stromstyrkor det fir fraga om, och strommen ledes till och frail matapparaten medelst grova kablar. Provningen sker genom att mata stromstyrka, eventuellt aven spanning vid olika varvtal och vid kortslutning (last motor) i enlighet med givna fOreskrifter. Inventor: G Akerblom Testing of the starter motor d a car can be done by booting the connection between the Indian railway and the starter motor and between these connect a feeder with an ammeter, possibly also a voltmeter. The feeder has a shunt for the main current from the battery to the starter motor; the shunt is dimensioned for the normal currents required, and the current is led to and frail the feeder by means of coarse cables. The test is performed by supplying current, possibly also voltage at different speeds and in the event of a short circuit (load motor) in accordance with given regulations.

Enligt den foxeliggande uppfinningen ar shunten .anordnad att anbringas direkt pa batteriets polbult. FOrhindelsen mellan batteriet och startmotorn brytes genom att den frail batteriet till startmotorn ledande kabeln med sin klamma lossa:s fran .den polbult, till vilken kabeln är ansluten; shunten anbringas darpa pa den sã frilagda polbulten, och den lossade kabeln anslutes med sin klamma till shunten. Man undviker harigenom anvandningen av de grova och ohanterliga, till matapparaten ledande kablarna. According to the present invention, the shunt is arranged to be mounted directly on the pole of the battery. The obstruction between the battery and the starter motor is broken by the frail battery leading to the starter motor cable with its clamp detaching from the pole bolt to which the cable is connected; the shunt is fitted tightly on the so exposed pole bolt, and the loosened cable is connected with its clamp to the shunt. This avoids the use of the coarse and unwieldy cables leading to the food appliance.

Shunten kan utera en fran matapparaten skild del, som anslutes till matapparaten medelst klena ledningar, eventuellt under anvandning av en stickpropp. Shunten kan emellertid aven vara sammanhyggd ailed matapparaten, sâ att denna tillsammans med shunten anbringas pa polbulten; nagra yttre ledningar for forbindning av shunten riled matapparaten erfordras Over huvud taget ej i detta fall. The shunt can perform a part separate from the food appliance, which is connected to the food appliance by means of small wires, possibly using a plug. However, the shunt can also be connected to the feeding apparatus, so that it is mounted on the pole bolt together with the shunt; no external wiring for connecting the shunt riled feeder is required at all not in this case.

Uppfinningen beskrives narmare i det fOljande med hanvisning till den bifogade nitaingen. Pa denna visar fig. 1 ett utforande av en shunt enligt uppfinningen, sedd Fran sidan, delvis i genomskarning. Fig. 2 visar shunten sedd uppifran. Fig. 3 visar ett forenklat kopplingsschema. Fig. 4 visar en shunt enligt uppfinningen, sammanbyggd med en elektrisk matapparat, och fig. 5 visar det tillhorande kopplingsschemat. The invention is described in more detail in the following with reference to the accompanying rivet. Fig. 1 shows an embodiment of a shunt according to the invention, seen from the side, partly in section. Fig. 2 shows the shunt seen from above. Fig. 3 shows a simplified wiring diagram. Fig. 4 shows a shunt according to the invention, assembled with an electric feeding apparatus, and Fig. 5 shows the associated wiring diagram.

I det i fig. 1 och 2 visade utforandet bestar shunten av tre delar, en del 2 for anslutning til hatteriets polbult, en del 3 for anslutning av den till startmotorn forande kabeln, och en del 4, shuntmotstandet, som i det visade utforandet bildas av fyra ,stavar 5, vilka genom hardlodning aro forenade med anslutningsdelarna 2 och 3. Till delarna 2 och 3 aro anslutna ledningar 6 och 7, vilka avslutas med en (ej visar) stickpropp for anslutning till matapparaten; endast Mena ledningar erfordras f5r ,denna anslutning. Delen 2 har en konisk urtagning 8, som passar till en normal polbult; for anslutning till en mindre polbult kan man anvanda en insatshylsa 9. Delen 3 har utvandigt konisk form; genom sin langd kan den anvandas for anslutning av kabelklammor bade fOr sma och stora polhultar. In the embodiment shown in Figs. 1 and 2, the shunt consists of three parts, a part 2 for connection to the pole bolt of the hatter, a part 3 for connection of the cable leading to the starter motor, and a part 4, the shunt resistor, which in the embodiment shown is formed of four rods 5, which by brazing are connected to the connecting parts 2 and 3. Wires 6 and 7 are connected to the parts 2 and 3, which are terminated with a plug (not shown) for connection to the feeding apparatus; only Mena wires are required for this connection. The part 2 has a conical recess 8, which fits a normal pole bolt; for connection to a smaller pole bolt, an insert sleeve 9 can be used. The part 3 has an externally conical shape; due to its length, it can be used for connecting cable clamps for both small and large pole holes.

Shunten kan exempelvis van av storleksordningen 1000A/120MV. The shunt can, for example, be of the order of 1000A / 120MV.

I prineip an verkningssattet ,detsamma nsom i det f6regaende beskrivet. Matapparaten .anbringas direkt pa batteriet med anslutningsdelen 2, och kabeln anslutes till kabelansdutrtingsdelen 3. Det tillhorande kopplingsschemat vis.asi fig. 5. Me-deist en stromstallare 10 kan .ett annat shuntmotstan:d 11 linkopplas for matning av den strom, som forbrukas av andra stromforbrukare i hilen. Med 12 beteeknas en polvandare. Aven i detta fall undviker man anvandningen av de grova kablarna. In the described embodiment, the ice shunt forms a separate part of the food appliance. In the embodiment shown in Fig. 4, the shunt is assembled with the feeding apparatus. In principle the mode of action, the same as in the foregoing described. The feeder is connected directly to the battery with the connection part 2, and the cable is connected to the cable extension part 3. The associated wiring diagram is shown in Fig. 5. With a current switch 10, another shunt resistor can be connected: d 11 is connected to the power consumed by other power consumers in hilen. By 12 is denoted a pole walker. Even in this case, the use of the coarse cables is avoided.
