Embodiment 1

[0051] This embodiment introduces the specific application of the catenary power supply device and method for thermal insulation of EMUs in stations, including main line catenary 10, arrival and departure catenary 9 and two catenary for thermal insulation of EMUs The power supply device 7, the main catenary 10 contains two main catenary power supply partitions 1001, and the catenary 9 to the distribution line contains a plurality of catenary power supply partitions 901 to the distribution line, and the voltage of the industrial power supply is 10kV;

[0052] The input terminal of the first isolating switch 2 of the catenary power supply device 7 for the thermal insulation of the EMU is connected to the 10kV power supply, and the third isolation of the catenary power supply device 7 for the thermal insulation of the EMU is first described. The input end of the switch 5 is connected to the first positive line catenary power supply partition 1001;

[0053] The input terminal of t...

Embodiment 2

[0059] The main difference between this embodiment and Embodiment 1 is that the two catenary power supply devices 7 used for thermal insulation of EMUs in Embodiment 1 can be combined into one, that is, there is only one catenary power supply device for thermal insulation of EMUs 7. Wherein the fourth isolating switch 6 is changed from 2 to 4, and the traction power supply is introduced from 2 positive line catenary to 1 positive line catenary.

[0060] The input terminal of the first isolating switch 2 of the catenary power supply device 7 used for the thermal insulation of the EMU is connected to a 10kV power supply, and the input terminal of the third isolating switch 5 of the catenary power supply device 7 used for the thermal insulation of the EMU is connected to the The first positive catenary power supply sub-area 1001 is connected;

[0061] The output end of the transmission branch line 13 of the catenary power supply device 7 used for the thermal insulation of the EM...

Embodiment 3

[0063] The main difference between this embodiment and Embodiment 1 is that this embodiment is the application of the catenary power supply device 7 for thermal insulation of EMUs in a parking lot.

[0064] Specifically, it includes the catenary 12 of the parking lot access line, the catenary line 11 of the car storage line, and two catenary power supply devices 7 for the heat preservation of the EMU, and the catenary 12 of the parking lot access line contains 2 parking lot access lines. The catenary power supply partition 1201, the catenary 11 of the car storage line contains 2 catenary power supply partitions 1101 of the car storage line; the catenary 12 voltage of the parking lot entrance and exit line is 25kV;

[0065] The input terminal of the first isolating switch 2 of the first catenary power supply device 7 used for EMU insulation is connected to the 10kV power supply, and the third isolating switch 5 of the first catenary power supply device 7 used for EMU insulation ...

Abstract

The invention provides a catenary power supply device for thermal insulation of EMUs and a power supply method thereof. The catenary power supply device for thermal insulation of EMUs includes an industrial power supply and a transformer (3), the industrial power supply and the transformer The input end of the device (3) is connected, and the transformer device (3) can change the voltage of the industrial power supply to an output voltage of 25kV and supply power for the arrival and departure catenary (9) or the parking line catenary (11). The catenary power supply device for thermal insulation of EMUs adopts the nearest common industrial power supply, transforms its voltage to 25kV, and connects to the catenary of the arrival and departure lines or storage lines of parked EMUs for thermal insulation of EMUs. It not only realizes the independent power supply to the arrival and departure line or the catenary of the parking line, but also avoids setting up a dedicated power supply line from the adjacent substation to the station, which can save a lot of engineering investment and operating costs.

Description

technical field [0001] The invention relates to the technical field of electric train set power supply equipment, in particular to a catenary power supply device for heat preservation of electric train sets, and a power supply method for heat preservation of electric train sets. Background technique [0002] When it is cold, in order to prevent the water parts of the EMUs parked on the departure line or parking line at the station from freezing, it is necessary to insulate the EMUs. The current heat preservation method is that the pantograph of the EMU draws power from the catenary, and the air conditioner and electric heat tracing components of the EMU are powered on accordingly. Fall naturally, and turn on the power when it drops to the predetermined temperature (8°C). [0003] If the catenary of the arrival and departure line of the parked EMU is in the same power supply zone as the catenary of the main line, when the main line is powered off at the skylight point for ma...
