Beneficial effect of the present invention is: the invention provides a kind of automatic cooling switch cubicle for fuse disconnecting switch, the cabinet of this switch cubicle is provided with ventilating opening, the cooling of switch cubicle is realized when there being wind, and cabinet both sides are provided with fan and temperature monitoring unit, the too high situation needing cooling of temperature in switch cubicle detected, unlatching fan, natural wind auxiliary under accelerate cooling rate, and break down at fan, situation slowly of lowering the temperature also can give the alarm signal, and reminding user is opened switch cubicle and dispelled the heat.
Accompanying drawing explanation
Below the content expressed by this Figure of description and the mark in figure are briefly described:
Fig. 1 is the operation principle structured flowchart of the automatic cooling switch cubicle for fuse disconnecting switch of the specific embodiment of the present invention.
Embodiment
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present invention is as the effect of the mutual alignment between the shape of involved each component, structure, each several part and annexation, each several part and operation principle, manufacturing process and operation using method etc., be described in further detail, have more complete, accurate and deep understanding to help those skilled in the art to inventive concept of the present invention, technical scheme.
The invention provides a kind of automatic cooling switch cubicle for fuse disconnecting switch, the cabinet of this switch cubicle is provided with ventilating opening, the cooling of switch cubicle is realized when there being wind, and cabinet both sides are provided with fan and temperature monitoring unit, the too high situation needing cooling of temperature in switch cubicle detected, unlatching fan, natural wind auxiliary under accelerate cooling rate, and break down at fan, situation slowly of lowering the temperature also can give the alarm signal, and reminding user is opened switch cubicle and dispelled the heat.
As shown in Figure 1, automatic cooling switch cubicle for fuse disconnecting switch comprises cabinet, fuse disconnecting switch, Temperature and Humidity unit, control unit, alarm unit and fan, fuse disconnecting switch, Temperature and Humidity unit, control unit, alarm unit and fan are installed in cabinet, cabinet is provided with air inlet and air outlet, natural wind is facilitated to dispel the heat, fan is arranged on air inlet, fuse disconnecting switch is arranged between fan and air inlet, Temperature and Humidity unit connection control unit is used for detecting the temperature and humidity in cabinet, the output of control unit connects alarm unit and fan, when the temperature in cabinet or humidity too high time, control unit sends heat radiation instruction to fan, fan turns dispels the heat.
The front and back of cabinet are made up of housing at four sides up and down, and left and right is ventilating opening.The left part of shell is air inlet, right part is air outlet, and fuse disconnecting switch is laid at the central cavity place of shell, and air inlet and air-out can allow wind pass from cabinet, increase radiating effect, it is inner between air inlet and fuse disconnecting switch that fan is arranged on air inlet.
Air inlet and air outlet just comparatively speaking, do not have absolute difference, and the setting box haul change of air inlet and air outlet, does not have stability, one end air intake, other end air-out, just just divide into air inlet and air outlet in order to description scheme is convenient herein.The housing of air inlet and air outlet is shutter, has gap between the curtain of shutter, and shutter comprises curtain and driving mechanism, curtain comprises control end, driving mechanism comprises temperature-sensitive extensible member, and temperature-sensitive extensible member has drive end, and drive end is connected with control end.When temperature-sensitive extensible member is heated, the drive end of temperature-sensitive extensible member expansion driven temperature-sensitive extensible member stretches out, and drive end drives control end motion control curtain to open.Opening or closing of driving mechanisms control curtain, when the temperature in cabinet is too high, temperature-sensitive extensible member expanded by heating drives the drive end of temperature-sensitive extensible member to stretch out, and drive end drives control end motion control curtain to open.When temperature like this in cabinet is too high, the curtain of shutter automatically will be opened and facilitate air intake to dispel the heat.
Fuse disconnecting switch adopts material filling type fusion tube, static-dynamic contact, secondary contact, arc-extinguish chamber, arc-chute, short trouble written instructions device, manual-operating mechanism and operation handle, be configured with short trouble written instructions device and manual-operating mechanism achieve reduce former slotting insurance failure rate, volume is little, lightweight, iron and steel parts all in switch all adopts antirust treatment, copper part top layer special processing smooth durable, contact good, manual-operating mechanism can by operating, handle realization divides, feed motion easily.Fuse disconnecting switch is arranged on the central cavity place in cabinet, can install multiple fuse disconnecting switch in cabinet, carries out temperature monitoring simultaneously, and multiple fuse disconnecting switch is positioned at a cabinet, reduces the cost of cabinet.
Temperature and Humidity cellular installation is in cabinet, connection control unit is used for detecting the ambient temperature in cabinet and humidity, ambient temperature in cabinet and humidity all affect the normal work of fuse disconnecting switch, so the temperature and humidity at fuse disconnecting switch place all needs to detect, Temperature and Humidity unit inspection to signal be sent in control unit, temperature threshold and humidity threshold is provided with in control unit, when the temperature-humidity signal data detected exceed the threshold value in control unit, control unit sends open command to fan, fan turns leaves the temperature in cabinet fast.When humidity is excessive time, fan also has certain loose tide effect.
In temperature in cabinet is too high, the temperature-sensitive extensible member of shutter is heated, the drive end of temperature-sensitive extensible member expansion driven temperature-sensitive extensible member stretches out, drive end drives control end motion control curtain to open, and fan is opened, rapid heat dissipation, successful, when temperature drops to below threshold value, shutter is closed, and switch cubicle is in normal condition.The alarm unit that control unit connects also can receive alarm signal when humiture exceedes Second Threshold, alarm unit give the alarm signal comprise warning lamp flicker or audible alarm, reminding user is initiatively opened switch cubicle and is dispelled the heat, Second Threshold is greater than temperature and humidity threshold value, when threshold range, switch cubicle can be settled a dispute by the parties concerned themselves heat dissipation problem, when humiture exceedes Second Threshold time, temperature and humidity on surface is too high, the work of cooling system is not enough to fast cooling, so the signal reminding user that gives the alarm.
Above by reference to the accompanying drawings to invention has been exemplary description; obvious specific implementation of the present invention is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present invention is conceived and technical scheme is carried out; or design of the present invention and technical scheme directly applied to other occasion, all within protection scope of the present invention without to improve.The protection range that protection scope of the present invention should limit with claims is as the criterion.
