Water Pumps Three Phase Voltage Monitoring Relay 380V protector 1CO 6A contact capacity
Phase sequence protector is a multi-function three-phase power system or three-phase power equipment monitoring and protection equipment.
The phase sequence protector can display the three-phase power
supply voltage in real time, and can output through the relay when
the power supply overvoltage protection, undervoltage protection,
phase loss protection, unbalance protection, fault phase
protection, PTC temperature protection, load side protection and
other faults occur. The form provides the user with an alarm output
and the contact control signal output by the protection circuit
action, which functions as an alarm and protection. Sets
three-phase voltage display, over-voltage protection, under-voltage
protection, phase loss protection (phase-failure protection),
voltage imbalance protection, phase sequence protection (wrong
phase protection) in one, using a powerful microprocessor chip and
non-easy Loss of storage technology, display using high-definition
ultra-wide temperature Chinese liquid crystal, with full-featured,
stable performance, intuitive display, easy operation.
Phase sequence protection device can be divided into two types: contact phase sequence protector and non-contact phase sequence protector. The former uses electromagnetic relays or AC contactors as its actuators, while the latter uses solid-state relays (thyristors, IGBTs, high-voltage VMOS transistors) as its actuators. The former uses the contacts of an electromagnetic relay or AC contactor to break the phase-sequence faulty three-phase power supply, while the latter uses an electronic component to turn off the faulty power supply. Therefore, compared with the former, the latter has the characteristics of fast response, no noise, no spark, long life, small size, and high mechanical strength. The former is relatively the latter, has a high breakdown pressure, withstand overload, low cost, etc. Features.
