Detailed Introduction

Performance characteristics
JJ1The self coupling pressure reducing control cabinet has complete control power: liquid level, pressure, temperature, time, linkage, and other multiple methods
The motor protection function is complete: multiple detection, reasonable design, compact structure, economical and practical for short circuit phase loss, overload, water leakage, overheating, etc

scope of application
1、JJ1Self coupling pressure reducing control cabinet suitable for AC communication50/60HzThe voltage is380Vdo380Vperhaps660VThe power is11～300KWThe three-phase squirrel cage induction motor is used for voltage reduction starting and can accelerate to electric modearriveRated speed and manual stop of electric power. It has overload, phase failure, short circuit and other protections for electric motors, and overload protection for starting time is installed for self transformers.
2、JJ1The performance of the self coupling pressure reducing control cabinet meets the requirementsIEC292-4、JB/DQ6187-86The relevant regulations.
3、JJ1The usage conditions of the autotransformer pressure reducing control cabinet:a.The maximum temperature of the surrounding air does not exceed+40℃The minimum temperature shall not be lower than-5℃；b.ambient air temperature24hThe average temperature does not exceed+35℃；c.The monthly average maximum temperature of the air is not very high90%The average temperature is35℃）；d.The altitude of the installation location shall not exceed2000Rice;e.The pollution level of the local micro environment around the starter cabinet shall not exceed3Grade.
