Abstract
The utility model relates to a ventilation control system of an electric power tunnel. The ventilation control system of the electric power tunnel comprises an axial flow fan, a fireproof valve, a fan control cabinet, an equipment monitoring cabinet and a main controller which are arrange inside a working well, wherein the axial flow fan and the waterproof valve are respectively connected with the fan control cabinet, and the fan control cabinet is connected with the main controller. Compared with the prior art, the ventilation control system of the electric power tunnel has the advantages of being timely and accurate in monitoring and the like.
Description
Technical field
The utility model relates to a kind of ventilated control system, especially relates to a kind of ventilated control system of electric power tunnel.
Background technology
Temperature is one of main determining factor that determines tunnel inner cable current-carrying capacity in the tunnel, and the transmission capacity that is directly connected to the tunnel inner cable can reach design load, satisfies system requirements.In addition, the maintenance personal need regularly enter the tunnel maintenance, and temperature can not be too high in the tunnel, for satisfying the temperature environment requirement of the normal operation of electric power tunnel, need carry out thermal equilibrium analysis to the tunnel.
Tunnel heat balance is exactly to analyze the various influence factors that get heat and loss of heat amount in the tunnel, electric power tunnel gets heat and is mainly the cable calorific value, tunnel loss of heat amount, the i.e. heat that outside tunnel structure, transmits, comprise by tunnel-side and soil biography heat earthward, start the heat that ventilation system is got rid of, and the tunnel surrounding soil absorbs the heat that stores behind the tunnel waste heat, and consider from the operation angle, the heat that the tunnel surrounding soil stores can discharge in the tunnel with spring and autumn in the winter time, becomes the tunnel and gets heat.Therefore, the tunnel thermal equilibrium analysis should be based upon on the basis of whole year operation.
Some ventilation equipment generally all have been installed in the existing cable tunnel, but how these equipment are carried out monitoring management, the general method of periodical inspection that adopts checks at present, but from economic angle and technical standpoint, scheduled overhaul has significant limitation.For example routine test and maintenance have caused very big direct and indirect economy waste, and many insulation defects and potential fault can't in time be found.
Summary of the invention
The purpose of this utility model is exactly the ventilated control system that a kind of monitoring electric power tunnel promptly and accurately is provided for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions: a kind of ventilated control system of electric power tunnel, it is characterized in that, comprise the axial flow blower, fire resisting damper, blower fan switch board, monitoring of tools cabinet and the master controller that are arranged in the active well, described axial flow blower is connected the blower fan switch board respectively with fire resisting damper, and the blower fan switch board connects master controller.
Per two axial flow blowers share a typhoon machine switch board, and the blower fan switch board is provided with the button of Control Shaft flow fan and the I/O interface of Long-distance Control on the spot.
Described blower fan switch board directly connects master controller.
Described blower fan switch board connects master controller by the monitoring of tools cabinet.
Described master controller also is provided with the interface that connects the fire alarm main frame.
Compared with prior art, the utility model system can discharge the heat that moisture in the tunnel and power cable operation are sent, and makes that ambient temperature and humidity maintains in certain scope the normal operation circumstances of guarantee cable in the tunnel; Safeguarding or constructor need enter the tunnel and carry out work the time, watering down pernicious gas in the tunnel by ventilation, guaranteeing the air quality in the tunnel; In the tunnel, during breaking out of fire, close blower fan, fire resisting damper.
Zone controller in the active well that is provided with the fire alarm main frame is reserved the interface with the fire alarm main frame, realizes the interlock of FAS (fire alarm system), BAS (automation control system).
Axial flow blower is set in the active well ventilates, adopt soft initiator to start, per 2 typhoon machines share a typhoon machine switch board, and control button and Long-distance Control I/0 interface on the spot are provided.
The blower fan switch board has on the spot/the telework status function selects, on the spot under the state by the button start and stop blower fan on the switch board, under the remote status by monitoring system Long-distance Control blower fan or automatically, interlock control blower fan.
