Problems solved by technology
[0002] In remote areas, power resources are transmitted over long distances, and there are often situations such as voltage drop and voltage instability, which cannot guarantee the accuracy of precise electrical test data; or the test data is lost due to sudden power failure during the test, or the data Errors will also cause the test to fail, or delay the debugging and work cycle, which will seriously affect the smooth progress of the power test, and will also cause large economic losses
And the sudden start and stop of the equipment caused by sudden power failure will affect the service life of the equipment and even cause equipment damage
In addition, the existing electrical workbench cannot provide direct lighting, and the site conditions are complex and there are many line equipment. If the test is carried out in addition to the electrical workbench, it also carries a mobile backup power supply and mobile lighting, which will cause chaos on the site, inconvenient operation and control, and affect the test efficiency. , and not very economical

Embodiment Construction
[0010] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. An electrical workbench with backup power supply includes an electrical test bench, a main power interface, a backup power supply and a power switching device, and the main power interface and the backup power supply are respectively connected to the power supply port of the test bench through the power switching device.
[0011] Such as figure 1 As shown, the backup power supply in this embodiment includes a battery connected in sequence, a capacitor filter circuit, a high-frequency full-bridge inverter circuit, a high-frequency transformer, a rectifier circuit, a capacitor filter circuit, a power frequency full-bridge inverter circuit and an LC filter circuit. The storage battery provides a stable DC voltage V1, the DC voltage V1 is filtered by a capacitor to obtain a voltage V2, and V2 is supplied to a high-frequency full-bridge inverter circu...

The present invention discloses an electrical workbench with a standby power supply. The workbench comprises an electrical test bed, a main power interface, a standby power supply and a power supply switching device; the main power interface and the standby power supply are connected with the power supply port of the test bed through a power supply switching device; and the standby power supply includes a storage battery, a capacitor filtering circuit, a high-frequency full-bridge inversion circuit, a high-frequency transformer, a rectifying circuit, a capacitor filtering circuit, a power frequency full-bridge inversion circuit and an LC filtering circuit which are connected in order. After a main power supply is interrupted, the standby power supply is automatically come into use, and after the main power supply is recovered, the main power supply recovers power supply, and therefore, the device damaging and data loss caused by sudden loss of power can be effectively avoided, the experiment efficiency is improved, and the service life of the device is prolonged.
Description
technical field [0001] The invention relates to the technical field of electrical testing instruments in power systems, in particular to an electrical workbench with a backup power supply. Background technique [0002] In remote areas, power resources are transmitted over long distances, and there are often situations such as voltage drop and voltage instability, which cannot guarantee the accuracy of precise electrical test data; or the test data is lost due to sudden power failure during the test, or the data Mistakes will also cause the test to fail, or delay the debugging and work cycle, which will seriously affect the smooth progress of the power test, and will also cause large economic losses. And the sudden start and stop of the equipment caused by sudden power failure will affect the service life of the equipment and even cause equipment damage. In addition, the existing electrical workbench cannot provide direct lighting, and the site conditions are complex and the...
