The utility model discloses a submersible pump starting protector, which is composed of a three-phase power supply A, B, C, a leakage protection circuit, an over-voltage protection circuit, an overload protection circuit, an execution circuit and a motor to be protected. One end of the leakage protection circuit Connected to the three-phase power supply, the other end is connected to the execution circuit; one end of the leakage protection circuit is connected to the three-phase power supply and the other end is connected to the execution circuit; the output of the execution circuit controls the motor to be protected.
The device uses A, B, C three-phase AC power supply into the leakage protection circuit and over-voltage protection circuit and the implementation of the circuit structure, with a large current, less components, low cost, simple circuit, good function, practicality and so on advantage. This patent project wants to transfer.
Inconel is a registered trademark of Special Metals Corporation for a family of austenitic nickel-chromium-based superalloys.
Inconel alloys are oxidation-corrosion-resistant materials well suited for service in extreme environments subjected to pressure and heat. When heated, Inconel forms a thick, stable, passivating oxide layer protecting the surface from further attack. Inconel retains strength over a wide temperature range, attractive for high-temperature applications where aluminum and steel would succumb to creep as a result of thermally induced crystal vacancies. Inconel's high-temperature strength is developed by solid solution strengthening or precipitation hardening, depending on the alloy.
