Description

Movable load device

Technical Field

The embodiment of the utility model provides a relate to power transmission and distribution equipment field, concretely relates to remove load device.

Background

Loads refer to the power and current passing in wires, cables and electrical equipment (transformers, circuit breakers, etc.). The load is not a constant value but a variable value that changes with time. Because the electric devices do not operate simultaneously, even if they operate simultaneously, they do not all reach the rated capacity at the same time. In addition, the operation system of each electric device is different, and the electric device has long-term, short-term and repeated short-term scores. In designing, if the capacities of the electric devices are simply added up as a basis for selecting the conductor, the cable section and the capacity of the electric device, the result is not scientific. Or the size is too large, so that the equipment is underloaded and uneconomical; or the size is too small, the overload operation is caused, the overheating insulation damage and the line loss are increased, the safe operation of a lead, a cable or electrical equipment is influenced, and a fire accident can be caused in severe cases. To avoid this, the design uses an assumed load, i.e. a calculation load, to characterize the total load of the system. In the power transmission and distribution operation, the checking operation is required to be carried out after the field installation of the metering device, and the checking operation is usually carried out by using a load device to assist in providing a simulated checking load.

The current load device is connected with the external power line in a plurality of ways, wherein the ways of connecting by using the pluggable connector are common, but the pluggable connector can be attached with more sundries between the plug and the socket in the long-term use process, so that the friction force between the plug and the socket is larger, when a user pulls out the plug, the force for pulling out the plug can not be well controlled, once the operation is not standard, the connection part between the plug and the external wire is easily torn off, and the plug can be pulled off in serious conditions, so that the load is in poor contact and the like.
