1.2 Conditions of use
1.2.1 Ambient temperature: -30~+40ºC;
1.2.2 Relative temperature: when the air temperature is +25ºC, the relative temperature is not more than 90%;
1.2.3 The oil temperature is not higher than 90ºC;
1.2.4 Places without severe vibration and turbulence;
1.2.5 The oil flow parameters of the transformer cooling system should be consistent with the flow parameters of the indicator (ie operating characteristics).
2 Main structure and working principle
2.1 Main structure The indicator is mainly composed of the display part composed of the dial 4 and the pointer
3, the signal switch part composed of the cam 2 and the micro switch 1, the transmission part composed of the moving plate 9, the transmission shaft 8, the return scroll spring 6 and the adjustment plate 7, and The coupling magnetic steel 5 is composed.
2.2 How it works When the oil pump of the transformer cooling system is started, the oil flow circulates, and when the oil flow reaches more than the action oil flow, the moving plate of the indicator is driven to rotate to the final position. position, the normally open contact of the micro switch is closed to send a normal working signal. When the oil flow is reduced to the return oil flow (or can not reach the action oil flow), the moving plate returns with the action of the reset scroll spring, so that the normally open contact of the micro switch is opened, and the normally closed contact is closed to send a fault signal.
