Resistor manufacturer

I. Purpose 1. The crane resistors for AC 50 Hz, low voltage up to 660 volts and a controller circuit (screen) with, to control the motor starting and braking. 2. Model significance: For example: a resistor with a crane cam controller KT10-25J / 1, continuous power is 40%; motor frame size 11,6 grade resistor made ZB2 resistive element, whose product model: RT11-6 / 1B. 3. Conditions:. A surrounding air temperature does not exceed + 40 ° C, the average temperature of the temperature within the 24-hour period does not exceed + 35 ° C, ambient air temperature limit of -25 ° C (temperature region) and -40 ° C (boreal regions). b. altitude does not exceed 2000m. c. the surrounding air clean, in + the highest temperature and 40 ° C and relative humidity not more than 50% relative humidity, lower temperatures can be increased (for example, + 20 ° C time by 90%, due to temperature changes, may occasionally produce light the degree of condensation). d. Install several other Class III, pollution degree 3. e. vertical installation, the slope does not exceed 5 °. II. Structure 1. Crane resistor according to standard a.RT Resistors -KT Cam control requirements can be made open, protection class IP00, can also be made enclosed, protection class IP12. 2. Crane Resistor varieties device. b.RK Resistors -KT cam controller, a phase open. c RS-type resistor -PQS type lift control panel control d.RY Resistors -PQY type pan controller e.RZ Resistors -PQZ type grab control panel control f.RP Resistors -PQHY belt translational control panel frequency relay control g.RQ resistors -PQ □ 6402PQ10 control panel to control the size and dimensions 3. Installation 4. Four tanks and four tank below the resistor can be directly stacked; five tanks and five boxes stacked above When installed, requiring mounted on a steel frame, when the spacing between stacked boxes is not less than 80mm, the middle can add insulation panels, spacing is too small to be lower capacity use, or use other appropriate measures.
