The frequency conversion control cabinet is an ordinary power cabinet or control cabinet that is changed from the traditional driving method to the frequency conversion driving method. In short: use frequency converter to drive the control cabinet of power unit. Because of its outstanding starting function, speed regulation function and energy-saving effect, it has become the current power drive method. Next, we will introduce the technical requirements and the primary application places of the down converter cabinet, hoping to help us.

Skill requirements for frequency conversion cabinet

1. Appearance and structure. Industrial robots shall be reasonably arranged, easy to operate, beautiful in shape and easy to maintain; No oil or gas leakage; Excellent smooth cooling; The mechanism shall be sensitive, stable and reliable.

Shielding, twisted pair and other anti-interference skills shall be adopted for signal wires; After a sudden power failure during movement, 2. electrical equipment. The power line and signal line shall be separated as far as possible. The power supply shall not be automatically connected when it is restored; The insulation resistance at the ungrounded position shall not be less than 5M Ω; Generally, electronic components shall be aged; The frequency conversion control cabinet shall have outstanding ventilation and heat dissipation measures; ± 10% of the power supply voltage fluctuation is allowed, and the frequency is allowed to be 50 ± 1HZ.

3. Reliability. Uniform time between failures (MTBF) and time to repair (MTP) are used as indicators to measure reliability.

4. Safety. The safety requirements shall meet the requirements of the Safety Code for Industrial Robots (GB1129189).

Primary applicable place of frequency conversion cabinet

1. Water supply system for urban and rural residential quarters.

2. Water supply for high-rise buildings, hotels and restaurants.;

3. Pressurization system of water plant and water supply station.

4. Deep well submersible pump water supply system and rural self built tap water system.

5. Reconstruction of the old water supply system (air pressure, water tower, high-level water tank).

6. Circulating water system in heating and air conditioning system.

7. Industrial constant pressure water supply system, industrial boiler water make-up system.

8. Adjustment and reconstruction system for insufficient water supply pressure of high-rise buildings.
