Abstract

The invention relates to the field of machinery and particularly relates to a load tester for a standby generating set. The load tester comprises a load box arranged on the base of the standby generating set. A resistance wire rack is placed flatwise in the load box and the resistance value of the resistance wire rack is 20-30% the power of the standby generating set. The load box is provided with a bottom plate and an air inlet is formed in the bottom plate. A fan is mounted at the air inlet, and the area of the air inlet is larger than the area of the fan. The wind generated by the fan blows to one side of the resistance wire rack with the surface area thereof to be largest and parallel to the fan. The motor of the fan is also mounted in the load box. Bar gratings are arranged on one side of the panel of the load box and the left and right sides of the load box respectively. The region of the bar gratings covers the resistance wire rack and is higher than the fan. According to the technical scheme of the invention, the no-load operation of the standby generating set during the testing process is avoided, and the running time thereof is prolonged. Meanwhile, the standby generating set is good in load radiating effect and stable in resistance value. the protection level reaches the IP 24-level and insulation level reaches the F-level. Moreover, the operation is simple and convenient and the manufacturing cost is low.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a load tester for a standby generating set. Background technique [0002] The power is supplied by the city power. When the power supply is cut off or the power supply is interrupted by other reasons, in order to ensure the basic production and life of the users, the backup generator is often used as the emergency power supply. Important power consumers such as industrial and mining enterprises, airports and TV stations with tight supply, and keep standby at any time. However, the long-term stand-by of the standby generator set will cause damage to itself, so it needs to be tested on-site every once in a while. The existing small and medium-sized standby generator sets are in no-load operation during the on-site test, and the no-load exceeds 10 minutes. The low idle speed or no-load will make the temperature of the combustion chamber too low and cause insufficient fuel combustion, which w...
