密度继电器安装：密度继电器安装在横梁中的汇流排上端接口，其电缆应用随设

Density relay installation: <br>The density relay is installed on the upper interface of the busbar in the beam. Its cable should be fixed on the beam with the clip provided with the device, and finally connected to the socket on the spring mechanism. <br>The circuit breaker is filled with SF6 gas: <br>The circuit breaker body has been filled with part of the SF6 gas before leaving the factory. There is no need to vacuum the single poles on site to remove moisture, but the air in the gas path connecting pipe must be eliminated, and the air in the gas path connecting pipe must be removed. Use the deflation tool to connect the SF6 gas cylinder to the charging valve, remove the packaging cover on the gas path, open the cylinder and blow with SF6 gas for 5 seconds, then immediately connect the gas path connecting tube to the charging valve on each single pole, and slowly Charge to rated pressure.

Density relay installation:<br>The density relay is installed at the upper interface of the busbar in the crossbeam, and its cable should be fixed to the crossbeam with a clip attached to the equipment, and finally connected to the socket on the spring mechanism.<br>Circuit breaker filled with SF6 gas:<br>The circuit breaker body has been partially filled with SF6 gas before leaving the factory. There is no need to vacuum and treat the water content of each single pole on site, but the air in the gas circuit connecting pipe must be removed. Use the provided charging and discharging tools to connect the SF6 cylinder to the charging valve, remove the packaging cover on the gas circuit connecting pipe, open the cylinder, and blow with SF6 gas for 5 seconds. Immediately connect the gas circuit connecting pipe to the charging valve on each single pole, and slowly charge to the rated pressure.

Installation of density relay:<br> The density relay is installed in the upper interface of the bus bar in the cross beam, and its cable is fixed on the cross beam with the clip of the equipment, and finally connected with the socket on the spring mechanism.<br> Circuit breaker filled with SF6 gas:<br> Part of SF6 gas has been filled into the circuit breaker body at the factory, so it is not necessary to vacuumize each monopole at the site. However, the air in the gas passage communication pipe must be removed, and the SF6 gas cylinder is connected with the inflation valve with the provided inflation and deflation tool, and the packaging cover on the gas passage communication is removed. After the gas cylinder is opened and blown with SF6 gas for 5s, the gas passage communication pipe is connected with the inflation valve on each monopole immediately, and it is slowly charged to the rated pressure.
