Qualitrol 130 Thermoplatte

m-l

Simulates winding temperature by using a proportional current transformer output to power a heating element contained in the well (pocket). Winding temperature is simulated by adding the rise due to the heater output to oil (liquid) temperature. All systems have at least one well for installation of a temperature indicator and/or measurement device (sold separately). Thermal plate is available with up to 3 wells and the 130 series is available with 1 well and up to 2 RTD’s.

Merkmale

Qualitrol Thermalplatten verfügen über Heizelemente aus einem geätzten Nickellegierungsgitter, das ausbruchsicher, beständig und stabil ist
Brass wells and die-cast Aluminum cases with thermosetting powder coat provide excellent protection from the elements
Simplify measurement of transformer winding and/or oil temperatures
Wells (pockets) and temperature probes with integrated heating elements provide an accurate simulation of the winding or hot spot temperature of the transformer based on transformer load, oil temperature, and heat rise constant from the transformer heat run
130 features a well with an integrated heating element and RTDs to produce a simulated winding temperature directly or by inserting other temperature measurement devices
Winding temperature simulation systems can be specified to work with either 1, 2 or 5 Amp CT inputs for transformer load sensing
Many auto balancing transformers, matching units, and trim resistors are available for other special CT and winding rise requirements. TRA-001 transformer can be used for CT currents up to 10 amps
Choose between one or two RTDs within the same 130, in either 100 Ohm (platinum) or 10 Ohm (copper) output
Both systems are designed to provide local and/or remote indication by accepting most Qualitrol bulb, capillary, or RTD based temperature sensing devices

Optionen

Verwendet eine universelle Sonde mit einstellbarer Länge und verschiedenen Hülsen zur Anpassung an unterschiedliche Durchmesser- und Längenbohrungen
Die Widerstandsthermometer der Serie 103 sind mit Pt100 (Platin 100Ω) oder Cu10 (Kupfer 10Ω) für die Verwendung mit Qualitol Thermalplatten Produkte erhältlich
Adjustable Resistor Assemblies allow easy calibration of the Thermal Plate’s heating element to your CT circuit
Der TRA-001-Transformator mit automatischer Symmetrierung passt den Eingang des Stromwandlers an den akzeptablen Bereich an, der erforderlich ist, damit das Heizelement die Wicklungstemperatur simuliert

Applications

For simulation of transformer winding temperature and/or measurement of oil (liquid) temperature. Qualitrol 130 can be used with a remote temperature sensing device and produces measurements directly with RTDs for remote indication and/or SCADA systems.
