Abstract

The invention discloses a multi-functional power supply device for a railway signal test. The device comprises a box body, a control panel is attached on the surface of the box body, electrical equipment is attached in the box body, the electric equipment comprises a DC 220V turnout power supply module, a 25HZ track circuit power supply module, a DC 24V relay power module, a 220V to 380V invertermodule and a transformer. The control panel is provided with eight sets of circuit breakers, five wiring terminal blocks, four ship-type switches, one power switch button sub switch, two AC220V wiringterminal columns, a cooling fan, three digital display indicators, a digital display ammeter, a digital display voltmeter, a three-phase AC power start button, a power input three-core aviation plug,a 25HZ track circuit phase tester, four buttons sub switches, and two 4-hole track wiring terminals. By applying the multi-functional power supply device, the construction risk coefficient is greatlyreduced, the engineering cost is reduced, and the driving safety is improved.

Description

technical field [0001] The invention relates to the technical field of railway business line reconstruction engineering, in particular to a multifunctional power supply device for railway signal testing. Background technique [0002] There are a lot of signal equipment renovation projects on China Railway's business lines every year, and a large number of new signal equipment and modified signal equipment need to undergo interlocking tests to verify that the equipment circuits are correct and work normally. Various signal equipment tests require a test power supply. Generally, the test power supply is imported from existing equipment or a temporary power supply is used. However, it is very difficult to obtain test power from existing signal equipment, and temporary power is also unreliable. Because signal equipment is the core control equipment of railway transportation, the use of existing signal equipment must be carried out within the blockade construction site, and the ...
