Description

Motorstroomregelaar NSE-wisselstellerNSE inverter motor current controller

De uitvinding heeft betrekking op het robuust maken van de Nederlandsche Spoorwegen Elektrische wisselstellers, afgekort de NSE-wisselstellers.The invention relates to making the Dutch Railways Electrical change counters robust, in short the NSE change counters.

Wisselstellers worden door spoorwegbeheerders gebruikt om wissels om te leggen en het treinverkeer gecontroleerd van spoor te laten veranderen.Interchangeable counters are used by railway managers to switch points and to have the train traffic change track in a controlled manner.

De toenemende intensiteit van het spoor dwingt de spoorwegbeheerder de spoorwegapparatuur robuuster te maken, ofwel de kans op storingen in het spoor significant te verlagen.The increasing intensity of the track forces the railway manager to make the railway equipment more robust, or to significantly reduce the chance of rail failures.

Wisselstellers en stangensets worden gebruikt om wissels om te leggen. Veel storingen zijn te wijten aan spoorwissels. Een wisselsteller is een onderdeel van een spoorwissel. Een van de punten van het robuuster maken van het spoor is het terugdringen van storingen en onderhoud aan de motorstroomkontakten van de NSE-wisselsteller.Switch counters and rod sets are used to switch turnouts. Many malfunctions are due to rail changes. A switch counter is part of a rail switch. One of the points of making the track more robust is the reduction of malfunctions and maintenance of the motor current contacts of the NSE inverter.

Een van de problemen van de NSE-wisselsteller is het inbranden van de motorstroomkontakten van de NSE-wisselsteller. De NSE-wisselstellermotor is een gelijkstroommotor. Bij het uitschakelen van de motorstroom wordt door het zware magnetische veld van de elektromotor een vonk getrokken over de zich openende motorstroomkontakten. Hierdoor branden de motorstroomkontakten in. Dit verschijnsel wordt vonkerosie genoemd en is voor de motorstroomkontakten de grootste bron van slijtage.One of the problems of the NSE inverter is the burn-in of the motor current contacts of the NSE inverter. The NSE inverter motor is a direct current motor. When the motor current is switched off, a spark is pulled over the opening motor current contacts by the heavy magnetic field of the electric motor. This causes the motor current contacts to burn out. This phenomenon is called spark erosion and is the greatest source of wear for the motor current contacts.

Het doel van deze uitvinding is een motorstroomregelaar te verschaffen die het vonken van de motorstroomkontakten vrijwel geheel opheft.The object of the present invention is to provide a motor current controller which substantially completely eliminates sparking of the motor current contacts.

De uitvinding betreft het plaatsen van een motorstroomregelaar tussen de klemmenstrook en de elektromotor over de motorstroomkontakten heen van de NSE-wisselsteller. De motorstroomregelaar tast met een stroomsterkte van enkele milliampères de stand van de motorstroomkontakten af en stuurt de elektromotor aan. Door de stroomsterkte van enkele milliampères, welke ongeveer lOOOx kleiner dan de stroomsterkte zonder motorstroomregelaar, is de vonkerosie over de motorstroomkontakten vrijwel geheel onderdrukt.The invention relates to the placement of a motor current controller between the terminal strip and the electric motor over the motor current contacts of the NSE inverter. The motor current controller scans the position of the motor current contacts with a current of a few milliamps and controls the electric motor. Due to the current intensity of a few milliamps, which is approximately 100x smaller than the current strength without motor current regulator, the spark erosion over the motor current contacts is almost completely suppressed.

De uitvinding zal nader worden toegelicht aan de hand van in een tekening weergegeven figuren, waarbij: • figuur 1: Motorstroomkontakten geleiden motorstroom • figuur 2: Motorstroomkontakten in het begin van de openingsbeweging • figuur 3: Motorstroomkontakten aan einde openingsbeweging en in rust • figuur 4: Vereenvoudigd elektrisch schema bestaande motorstroomsturing • figuur 5: Vereenvoudigd elektrisch schema motorstroomsturing met ingebouwde motorstroomregelaarThe invention will be further elucidated on the basis of figures shown in a drawing, wherein: • figure 1: Motor current contacts guide motor current • figure 2: Motor current contacts at the beginning of the opening movement • figure 3: Motor current contacts at the end of the opening movement and at rest • figure 4 : Simplified electrical diagram for existing motor current control • Figure 5: Simplified electrical diagram for motor current control with built-in motor current controller

In figuur 1 zijn de motorstroomkontakten [1] weergegeven. In deze stand wordt de elektrische stroom door de motorstroomkontakten [1] geleidt. In de bestaande motorstroomsturing is de motorstroom ongeveer 6 ampère bij 110 volt gelijkstroom.Figure 1 shows the motor current contacts [1]. In this position the electrical current is conducted through the motor current contacts [1]. In the existing motor current control, the motor current is approximately 6 amperes at 110 volts direct current.

In figuur 2 worden de motorstroomkontakten [1] door de mechanische beweging abrupt verbroken aan het begin van de openingsbeweging. Het magnetisch veld in de elektromotor is niet plotsklaps weg en trekt nog even een elektrische stroom achter zich aan. Dit veroorzaakt een stroomvonk door de lucht over de zich openende motorstroomkontakten. Deze stroomvonk landt op het kontaktoppervlak en veroorzaakt aldaar een kratertje doordat het metaal van het kontaktoppervlak door de elektrische vonk wordt weggebrand. Dit gebeurt elke keer als de elektromotor door de motorstroomkontakten wordt uitgeschakeld. Dit verschijnsel wordt vonkerosie genoemd.In Figure 2, the motor current contacts [1] are abruptly broken by the mechanical movement at the start of the opening movement. The magnetic field in the electric motor is not suddenly gone and draws an electric current behind it. This causes a current spark through the air over the opening motor current contacts. This current spark lands on the contact surface and causes a crater there because the electric spark burns away the metal from the contact surface. This happens every time the electric motor is switched off by the motor current contacts. This phenomenon is called spark erosion.

In figuur 3 zijn de motorstroomkontakten [1] aan het einde van de openingsbeweging en zijn in rust. De motorstroom is nu geheel uitgeschakeld.In Figure 3, the motor current contacts [1] are at the end of the opening movement and are at rest. The motor current is now completely switched off.

In figuur 4 is het vereenvoudigd elektrisch schema weergegeven van de bestaande motorstroomsturing in de NSE-wisselsteller. De motorstroomkontakten [2] zitten tussen de elektromotor [3] en de klemmenstrook [4].Figure 4 shows the simplified electrical diagram of the existing motor current control in the NSE inverter. The motor current contacts [2] are located between the electric motor [3] and the terminal block [4].

In figuur 5 is het vereenvoudigd elektrisch schema weergegeven van een motorstroomregelaar [5] tussen de klemmenstrook [4] en de elektromotor [3] over de motorstroomkontakten [2] heen. De motorstroomregelaar [5] tast de stand van de motorstroomkontakten [2] af met een stroomsterkte van enkele milliampères. Deze stroom is zo klein (ruim lOOOx kleiner dan zonder motorstroomregelaar) dat het vrijwel geen vonkerosie veroorzaakt en de motorstroomkontaken [5] dus een significant langere levensduur krijgen en ook minder of geen onderhoud nodig hebben.Figure 5 shows the simplified electrical diagram of a motor current controller [5] between the terminal strip [4] and the electric motor [3] over the motor current contacts [2]. The motor current controller [5] scans the position of the motor current contacts [2] with a current of a few milliamps. This current is so small (more than 100x smaller than without a motor current controller) that it causes virtually no spark erosion and the motor current contacts [5] therefore have a significantly longer service life and also require less or no maintenance.

De NSE-wisselsteller is door de motorstroomregelaar [5] robuuster geworden. De motorstroomkontakten blijven significant langer in topconditie en veroorzaken vrijwel geen storingen meer als gevolg van overmatige slijtage door vonkerosie.The NSE inverter has become more robust due to the motor current controller [5]. The motor current contacts remain in peak condition significantly longer and cause virtually no more malfunctions due to excessive wear due to spark erosion.
