Sell Sf6 Manometer

 

SF6 (with alarm devices) pressure control is mainly applied to the instrument with the corresponding electrical devices (such as relays and contacts, etc.) supporting the use can be measured on the (control) pressure system to achieve automatic control and letters (alarm) purposes. The main application of high-voltage power distribution switches, high-voltage power distribution equipment, such as power transformers in the electrical engineering, to monitor SF6 gas pressure. When confined system of SF6 gas leakage occurred from time to time by SF6 pressure controller output signal alarm and atresia. SF6SF6 (with alarm devices) are often configured pressure control switch set two points P1 and P2, P1 for the alarm set point, set point for P2 atresia point. When the system SF6 gas leakage, as the SF6 gas reduction target of Contact (a contact), and configure the switch contact point P1 (the contact) contacts issued warning signal Along with the gas fall, when contact with the target set on the contact point P2 contact, the signal sent atresia, the circuit breaker switch to shut down automatically, so that they will not work to prevent accidents.
