BWY (WTYK)-803, 802 series pressure type temperature indicating controller (hereinafter referred to as temperature controller) is mainly designed for measuring and controlling the oil temperature of large power transformers, and also used for temperature detection and control of other equipment.
This series of thermostats have good protective performance and can work normally for a long time under outdoor conditions. The instrument is equipped with two or three sets of large-capacity temperature control switches, which can be used for the startup, shutdown and signal alarm of the transformer cooling system respectively.
serial number | Model and name | The main purpose | Applications |
1 | BWY (WTYK)—803, 802 Thermostat | Measure the oil temperature of the top layer of the transformer and start, shut down the cooling system and send an alarm signal when the temperature reaches the set value | Transformers above 1000kVA |
2 | BWY (WTYK)—803, 802 (TH) thermostat | Same as 1 And suitable for wet tropical occasions | 1000kVA above transformer |
3 | BWY (WTYK)—803, 802A (TH) thermostat | Same as 2; and adopts composite temperature sensor technology, which can output Pt100 thermal resistance signal at the same time | 8000kVA above transformer |
4 | XMT Digital temperature controller | It is matched with BWY (WTYK)-803 and 802A to realize remote measurement and remote control of oil temperature. It can also output standard signals for networking with computers | 8000kVA above transformer |
5 | BWY (WTYK)—803, 802A/XMT thermostat | The same as 3, 4, etc. can be replaced at the same time 1) WTZK-02 thermostat 2) Resistance thermometer 3) Transfer switch 4) Self-meter form such as XCT or XMT 5) Transmitter | Transformers above 8000kVA or unattended substations |
