Description
Technical Field
[0001] The utility model belongs to the technical field of the operating conditions of generator sets, and relates to an operating condition indicating device for a motor - generator set in a pumped - storage power station. Background Technique
[0002] During the daily production activities of a pumped - storage power station, two operations of power generation and pumping are required. Currently, the commonly used motor - generator sets in pumped - storage power stations integrate generators and pumping water pumps together, and one set of units can achieve two functions. Its operating conditions include power generation, shutdown, pumping, phase regulation, etc. The operating conditions of the units in a pumped - storage power station are more diverse than those of traditional power stations. Due to the "daily regulation" characteristic of the load in a pumped - storage power station, the conversion of the daily operating conditions of the units is more frequent. The same set of units often needs to perform multiple power generation and pumping operations within a day. Different unit operating conditions have a greater impact on the on - site staff's operations. Clear and accurate condition indication can ensure the personal safety of workers during operations and prevent accidental injury incidents. The existing unit condition indication devices have the following disadvantages and inconveniences:
[0003] 1. The switching between condition display modes is rather rigid, and the state during the conversion of the two conditions of the unit cannot be displayed.
[0004] 2. The function is single, only indicating the unit state through different lamp colors, and unable to indicate the relevant operating parameter information of the unit. Summary of the Invention
[0005] The technical problem to be solved by the utility model is to provide an operating condition indicating device for a motor - generator in a pumped - storage power station, which can display the state during the conversion of the two conditions of the unit and indicate the relevant operating parameter information of the unit.
[0006] To solve the above - mentioned technical problem, the technical solution adopted by the utility model is: an operating condition indicating device for a motor - generator in a pumped - storage power station, which includes a semi - transparent soft - light housing, a color LED light strip, a PLC control module, a power supply module, a basic base, and a display screen; the semi - transparent soft - light housing and the color LED light strip are connected to the basic base, and the color LED light strip, the power supply module, and the display screen are electrically connected to the PLC control module; the PLC control module makes logical judgments and issues corresponding indicator light display signals.
[0007] The basic base is a hollow inverted - cone structure, with a cross - shaped rib plate arranged at its center. The L - shaped bracket is connected to the cross - shaped rib plate, and a top plate is arranged above the cross - shaped rib plate.
[0008] The semi - transparent soft - light housing is an annular structure and is connected to the L - shaped bracket.
[0009] The color LED light strip is located at the angle of the L - shaped bracket and is connected to it.
[0010] The power supply module and the PLC control module are located inside the basic base, and the display screen is located above the top plate and connected thereto.
[0011] The main beneficial effects of the present utility model are as follows:
[0012] After the PLC control module (3) starts and runs normally, the device can perform display output according to the signals of the unit's local control cabinet through the built-in program logic judgment. When an operating condition ends, there is no need for manual reset intervention for the device. The internal program of the PLC control module (3) in the pumped-storage motor-generator set operating condition indicating device will automatically reset to the previous condition and perform the display of the next condition according to the instructions of the unit's local control cabinet, display the state during the conversion of the two operating conditions of the unit, and indicate the relevant operating parameter information of the unit.

[0020] As Figures 1 - 5 shown in, an operating condition indicating device for a pumped-storage power station generator motor includes a semi-transparent soft light housing 1, a color LED light strip 2, a PLC control module 3, a power supply module 4, a basic base 5 and a display screen 6; the semi-transparent soft light housing 1 and the color LED light strip 2 are connected to the basic base 5, and the color LED light strip 2, the power supply module 4 and the display screen 6 are electrically connected to the PLC control module 3; the PLC control module 3 performs logic judgment and issues corresponding indicator light display signals.
[0021] Preferably, after turning on the display power supply, wait for the PLC control module 3 to start running. After the PLC control module 3 starts running normally, the device can perform display output according to the signals of the unit's local control cabinet through the built-in program logic judgment. When an operating condition ends, there is no need for manual reset intervention for the device. The internal program of the PLC control module 3 in the pumping and generating motor unit operating condition indicating device will automatically reset the previous condition and perform the display of the next condition according to the instructions of the unit's local control cabinet.
[0022] Preferably, the indicator lights externally display the condition information through the color LED strip 2. The color LED strip 2 independently arranges red, yellow, green, and white monochromatic light-emitting beads. The semi-transparent soft light shell 1 can evenly display the light to avoid light pollution.
[0023] Preferably, the PLC control module 3 controls the display color and mode of the color LED strip 2, and the custom display content of the display screen 6, and its input signal is taken from the local control cabinet of this unit.

The L-shaped bracket 51 is connected to the cross rib plate, and a top plate 52 is arranged above the cross rib plate. During use, the top plate 52 covers the upper part of the L-shaped bracket 51, which is equivalent to the top cover of the slip ring chamber; at the same time, it blocks the light leaking from the upper end of the slip ring chamber, and the light can only be transmitted through the semi-transparent soft light shell 1.
[0026] Preferably, a pin is arranged on the outer side of the L-shaped bracket 51, and the pin is inserted and connected to the pin hole on the cross rib plate.
[0027] In a preferred solution, the semi-transparent soft light shell 1 is an annular structure and is connected to the L-shaped bracket 51.

During installation, the color LED strip 2 is installed and fixed at the angle of the L-shaped bracket 51, so that its light irradiates towards the semi-transparent soft light shell 1.
[0030] Preferably, the color LED strip 2 displays lights of multiple colors including white, red, green, and yellow.
[0031] In a preferred solution, the power supply module 4 and the PLC control module 3 are located inside the base pedestal 5, and the display screen 6 is located above the top plate 52 and connected thereto. During use, the power supply module 4 and the PLC control module 3 are placed inside the base pedestal 5, and the display screen 6 is installed on the top plate 52, saving overall space.
[0032] Preferably, the base pedestal 5 is located inside the slip ring chamber, and the PLC control module 3 and the power supply module 4 are centrally arranged in the control box inside the slip ring chamber, facilitating data and power connection. The power supply of this display screen 6 can be taken from the common power distribution cabinet of this unit; the display screen 6 operates fully automatically without manual intervention, and the relevant signals of the unit operation state are transmitted from the on-site control cabinet of the unit to the PLC control module 3, and the PLC control module 3 makes logical judgments and issues corresponding indicator light display signals.
[0033] Preferably, the red light is always on in the power generation condition; the green light is always on in the pumping condition; the yellow light is always on in the phase modulation condition; the white light is always on when the unit enters an indeterminate state; when the unit has a relatively serious fault, the red light and the yellow light flash intermittently, and the buzzer emits an alarm sound; the user can customize the unit operation data on the display screen according to usage habits, facilitating on-site personnel to observe.
