Abstract
The utility model discloses a fan control box for a photovoltaic power station. The electric loop of the main body of the fan control box comprises a primary control loop and a secondary control loop, wherein the primary control loop is provided with a circuit breaker QF and a contactor KM1 normally open contact; the circuit breaker QF and the contactor KM1 normally open contact are connected to a fan set in series; the secondary control loop is provided with a hand switch K1, a temperature controller KH and a contactor KM1 coil; the automatic temperature control switch of the temperature controller KH is connected with the hand switch K1 in parallel and then is connected with the contactor KM1 coil in series to form a first control circuit; the first control circuit is connected with the temperature controller KH in parallel and then is connected to a storage battery by a fuse FU; and the storage battery is connected with a solar cell panel. The fan control box solves the problems of over-long laying range of an inverter chamber fan control power supply in the photovoltaic power station and over-large inspection task load.
Description
Technical field
The utility model relates to a kind of photovoltaic station fan control box, is mainly used in the control of photovoltaic plant on-site inverter chamber ventilated and uses.
Background technique
The at present construction of photovoltaic plant is more and more, and capacity is increasing, and along with the continuous increase of place, it is increasing that the Ventilation Control power supply of on-site inverter chamber lays scope, and the patrol task amount is just increasing.
Summary of the invention
The utility model is in order to overcome the above problems, and provides a kind of and can solve in the photo-voltaic power generation station inverter chamber air-blower control power supply to lay scope long, the photovoltaic station fan control box of patrol task amount problems of too.
The technical solution of the utility model is: photovoltaic station fan control box, its difference is: its main body electric loop comprises control loop one time, secondary control loop, one time control loop is provided with circuit breaker Q F and contactor KM1 normally opened contact, circuit breaker Q F and contactor KM1 normally opened contact are connected serially to the blower fan group, secondary control loop is provided with hand switch K1, temp controller KH, contactor KM1 coil, wherein, connect with contactor KM1 coil after the automatic temperature control switch of temp controller KH and the hand switch K1 parallel connection and consist of first control circuit, first control circuit be connected to storage battery by fus FU again after temp controller KH is in parallel, storage battery is connected with solar panel.
The beneficial effects of the utility model are: the power generation characteristics of considering photovoltaic plant, be the only 9:00-15:00 when fine weather of generating dutation, the time response of learning fan operation meets the photovoltaic generation characteristic, adopt sun-generated electric power as the control power supply of control box at this, having greatly reduced power supply takes from the caused long-distance cable of booster stations and lays, and the employing clean energy resource has been saved energy consumption greatly.Adopt casing built-in temperature controller, realized on the one hand the automation of indoor fan control, the personnel of patrolling and examining can namely recognize the room temperature situation outdoor on the other hand, have greatly reduced the patrol task amount, also to a certain degree guaranteed the personnel's that patrol and examine safety.
Description of drawings
Fig. 1 is the utility model external structure schematic representation;
Fig. 2 is the A-A sectional view of Fig. 1;
Fig. 3 is electrical wiring schematic diagram of the present utility model.
Embodiment
Further specify the utility model embodiment below in conjunction with accompanying drawing.
As shown in Figure 1 and Figure 2, the utility model embodiment photovoltaic station fan control box, comprise casing 1, be provided with door lock 2, nameplate 3 in casing 1 front, and a transparent window 4 is set specially, the personnel of patrolling and examining can see through this window and check that the temperature inside the box shows that conveniently the personnel of patrolling and examining inspect the inverter room temperature, ensure to patrol and examine personnel's personal safety.
Referring to Fig. 3, the utility model embodiment photovoltaic station fan control box, its main body electric loop comprises control loop one time, secondary control loop, one time control loop is provided with circuit breaker Q F and contactor KM1 normally opened contact, circuit breaker Q F and contactor KM1 normally opened contact are connected serially to the blower fan group, secondary control loop is provided with hand switch K1, temp controller KH, contactor KM1 coil, wherein, connect with contactor KM1 coil after the automatic temperature control switch of temp controller KH and the hand switch K1 parallel connection and consist of first control circuit, first control circuit be connected to storage battery by fus FU again after temp controller KH is in parallel, storage battery is connected with solar panel.
Circuit breaker is closed state generally speaking, and the main protections such as the short circuit current protection of current supply circuit realize by circuit breaker, contactor only as the switch loop usefulness.Under the normal working, hand switch disconnects, by the folding of temperature detect switch (TDS) automatic control loop, namely when temp controller detected the inverter room temperature greater than 35 degrees centigrade, temperature detect switch (TDS) KH was closed, and contactor KM1 relay circuit is connected, the KM1 action makes fan operation.Hand switch is opened when the personnel of patrolling and examining patrol and examine according to actual requirement operating switch K1, thereby realizes the start-stop of control blower fan.
