When load bank need to be disconnected, the control system will automatically send instructions, and second protection will be finished by main circuit.
(1)Over Voltage Protection (12kv): The input load voltage is over the safe threshold value, system unload automatically and alarm.
(2)Short Circuit Protection and Over Current Protection: when short circuit, fuses protect to unload automatically.
(3)Overheating Protection (150ºC): Temperature is over the safe threshold value, system unload automatically and alarm.
(4)Smoke Fog Protection: If there is smoke fog in the container, system unloads automatically and alarm.
(5)Fan Delivery Protection: If insufficient air volume of any fan is below 2450m³/h, system unloads automatically and alarm.
(6)Overload protection with fan: When any fan cannot normally work, the load bank can unload automatically and alarm.
(7)Emergency Stop: Manually press the Emergency Stop switch on the panel, load bank will be in locked state, and cannot do any operation.
(8)Protection Switch: Some protection with switch, when misinformation or in special need, operator can close the corresponding protection function temporarily.
(9) Safety Monitor: Get through indicator lights on main interface, Operator can monitor system state. When system abnormally stop and be protected, software interface prompt the cause immediately.

7. Resistive Load Introduction
Resistive load consists of special alloy resistors. There is cooling fin outside, filled with insulation medium, resistor is in insulation medium, it can meet load testing requirements. Alloy resistor is with high insulation performance, uniform heat conduction. Running temperature is only 1/3 of designed temperature, low temperature drift, steady resistance, no red-hot in long time running. Acid alkaline resistant, salt fog resistant, waterproof, moisture proof, anti corrosion for all weather use. With exclusive technology, alloy resistor is fixed in insulated material palette; the whole resistive load is blocked, insulated by inner insulation and insulation plate, make sure the good insulation and safety even in wet weather and prevent short circuit because of next resistor value decreases.
(1) Alloy resistor is Aluminum-niobium-cobalt (Co21Al6NB), anti temperature (max working temperature reach up to 1500ºC), steady electrical performance, low temperature drift (5*10-5/ºC), this technology is the most advanced in alloy resistor manufacturing.
(2) The materials of resistor strictly use low extensibility and resistance oxidation Stainless Steel 321 (1Cr18Ni9Ti), filling material export grade electrical crystallization magnesium oxide powder (Sg-9), performance standards JBY-TE4088-199, magnesite density 3.0g/cm3±0.2, screws is anti-corrosion, anti-temperature Stainless Steel 304(0Cr18Ni9). With strict and clear material control, the mass produced alloy resistor are with highly congruent performance.
(3) Cooling fin Stainless Steel 321, height 7mm±2, thickness 0.4mm±0.2, winding interval no more than 3mm±0.2.
(4) When each resistor withstand voltage is DC3000V or 1500V, 50Hz, 1 minute without puncture. Real voltage is 1/3 of withstand voltage, make sure the resistor in good working condition without puncture.
(5) Cooling fin uniform temperature no more than 300ºC, max 320ºC, there is enough margin to make sure alloy resistor can be working continuously, resistor max temperature 1500ºC.
(6) When resistor temperature reach 300ºC to 400ºC, temperature drift is also less than ±2%, it assure the resistance value no much changes in high temperature working condition, thus loading steady power could be available in any temperature.
(7) Whether in max and min temperature, load accuracy is no more than 3%
(8) Each resistor tube resistance value tolerance: no more than ±1.5%.
(9) Air outlet temperature no more than 80ºC (within 1 meter)
