. . 3. Resistive load module alloy power resistor Rod
. . The resistive load module is made up of several special alloy resistors connected together. As a power consumption component, alloy resistors are processed and manufactured from special alloys. The outside is a heat sink and the middle is filled with an insulating medium. The resistor is packaged in it to meet the needs of load testing.
. . .Alloy resistance has good insulation performance, high heat dissipation performance, uniform heat conduction, operating temperature is only the design temperature and small temperature drift, stable resistance value, and no red heat during long-term operation. It is acid-resistant, salt spray-resistant, rain-proof, moisture-proof and corrosion-proof, and can be used all day long.
. . .The resistive load module uses technology to fix the alloy resistor on the insulating material board. The entire module is sealed and separated by internal insulation and insulation boards to ensure insulation and safety even in humid weather. property, and can prevent short circuit accidents caused by the decrease in internal resistance of adjacent resistors.
. . .4. Inductive load module reactor
. . .The inductive load module is composed of several fixed reactors. Its main purpose is to adjust the inductive load during the load test and cooperate with the resistive load. The load power factor can be adjusted to simulate the actual working status of the generator set.
. . .The fixed reactor is made of a fixed iron core and three-phase copper windings (aluminum wire can be used here). It is manufactured with advanced technology and treated with waterproof, salt spray and mold resistance. The iron core is made of high-quality cold-rolled oriented silicon steel sheets, and the air gaps are separated by epoxy layer glass cloth plates to ensure that the reactance air gap does not change during operation. The coil and iron core of the reactor are assembled into one and then pre-baked, air-dipped in paint, and dried and cured to firmly combine the coil and iron core of the reactor. It has small loss, high efficiency, low temperature rise, and can operate stably for a long time under rated load. No noise, no pollution, no need for daily maintenance and long service life.
