Description
Technical Field

Background
In recent years, with rapid expansion of the scale of power grids and continuous improvement of maintenance technologies in the power industry, mobile maintenance power supplies on operation sites are increasingly required in power construction or maintenance operations. At present, the electric energy of a mobile maintenance power supply used on an electric power operation site is usually taken from a maintenance power supply box, a diesel generator, a mobile power supply vehicle or other standby power supplies, and the following problems may occur in the electric energy acquisition process:
1) the external power supply is single. The method is applied to the operating places without external power supplies, such as power failure of all stations of a transformer substation, incapability of normally supplying power for station transformers, power transmission lines, power distribution station areas and the like. At this time, a diesel generator is generally used for generating power to provide a maintenance power supply, but the quality of the power supply provided by the diesel generator is poor, and inaccurate test results (such as dielectric loss factor, direct current leakage test and the like) may be caused when certain specific tests are performed. And the problems of interference to residents due to excessive noise, environmental pollution and the like exist when the diesel generator is used for supplying power in the power transmission line and the power distribution station of the residential area.
2) The power output is of a single type. The mobile maintenance power supply widely used at present directly transfers an external mains supply to electric equipment.
3) There is no monitoring alarm function. The existing mobile maintenance power box is lack of detection of electric energy input and output states (voltage, current and the like), and when a maintainer uses the power box each time, the maintainer does not know the current and voltage value of an input side and does not know the current and voltage value of an output side, and the data are lack of monitoring, so that the fine requirements of current maintenance and test work cannot be met.
4) And the self-checking function of the emergency power supply is lacked. Under the condition of total station voltage loss, the traditional mobile maintenance power box can only rely on a temporary power supply provided by an external generator to get electricity, but the quality of electric energy provided by the generator is poor, the power supply requirements of some testing instruments cannot be met, the test result of the testing equipment is often inaccurate, and even the risk of damaging precise instruments is caused.
