The dustproof dehumidifying of above-mentioned enclosed busbar care device, described control circuit also comprises pressure control table, its detecting head is for measuring the pressure of closed system, and output control terminal connection hot air apparatus ajutage valve, with by-pass valve control aperture.
Accompanying drawing explanation
Fig. 1 is the electrical schematic diagram according to the dustproof dehumidifying of a kind of enclosed busbar of the present utility model care device main circuit, comprises the transformation part of control circuit in figure.
Fig. 2 is according to the electrical schematic diagram of the dustproof dehumidifying of a kind of enclosed busbar of the present utility model care device control circuit, omits transformation part in figure.
Embodiment
With reference to explanation accompanying drawing 1, use the well heater 2 of three-phase electricity, same, about heating, as used resistance element heating, single-phase electricity can be used as power supply equally.In well heater, is furnished with temperature acquisition element, thermopair TP as shown in FIG..Main circuit adopts A.C. contactor KM to control, and string has circuit breaker Q F1, to protect main circuit.
Control circuit has main circuit to draw, and also can configure independently control circuit, those skilled in the art will appreciate that in most cases, and control circuit is directly drawn mutually from one of main circuit, does not repeat them here.
Control circuit comprises some low voltage components, carries out transformation by transformer TR.
Control circuit carries out power supply indication by pilot lamp HL, and pilot lamp HL can seal in the major loop of control circuit, also can adopt other set-up mode, such as certain loop in on-state all the time that seals in control circuit.
In Fig. 2, first control loop is the configuration of current routine, the namely loop of temperature control table TC, by rotary switch, S1 controls, and is going here and there and having a combination switch, namely control model switch thereafter, it comprises two switches parallel with one another, one of them is rotary switch SH, and for manual control, another is contact KH, referring to the RH A loop of accompanying drawing 2, that output is controlled is exactly contact KH.Introduce accordingly Temperature and Humidity Control table RH A, represent the Temperature and Humidity Control table of A phase, other are referring to structure as shown in Figure 2, comprise three tables, control the humiture of three-phase, three's parallel connection, all export and control contact KH, thereby produce another kind of state of a control, namely automatic control state, hand control and automation the convenient debugging of the state of depositing and normal use.
Parallel connection also means that any phase humiture index is not up to standard, just need adjust well heater.
In the structure shown in Fig. 2, contact KA has also been gone here and there in the loop of temperature control table, and next-door neighbour's structure is pressure control table loop, and the namely contact KA of a pair of contact that its output is controlled, so as to by the state of pressure control temperature controller.
In addition the probe of temperature control table TC, namely temperature sensor is arranged in heater H RT, for measuring the hot blast temperature of discharge, the pressure and temperature of the air draft of control heater that so just can be comprehensive.
The aperture of controlling YV1-YV3 valve is exported in pressure control table simultaneously, thus controlled pressure and flow.
Current as temperature control table, can carry out directly output and control by bound is directly set, very convenient.
For another example Temperature and Humidity Control table, its setting can be with reference to following setting means:
Press ' SET ' key humidity LED and show [LLLL], represent to enter lower limit set state, temperature LED display setting value, button is selected the figure place of setting value, by ▲ setting value increase, reduce by ▼ setting value, lower limit set is complete, again press ' SET ' key, now humidity LED shows [LL01], represents that entering lower limit returns stagnant set condition.Button selects to set figure place, by ▲ setting value increase, reduce by ▼ setting value, show [HHHH] by ' SET ' humidity LED again, represent to enter upper limit set condition, temperature LED display setting value, button is selected the figure place of setting value, by ▲ setting value increase, press ▼ setting value and reduce, lower limit set is complete, again presses ' SET ' key, now humidity LED shows [HH01], represents that entering the upper limit returns stagnant set condition.Button selects to set figure place, increases by ▲ setting value, reduce by ▼ setting value, when bound and return stagnant amount setting complete after, again press SET key, exit set condition, start to enter observing and controlling state.
Control explanation: all control is stagnant for starting back, the control of routine humidity lower limit: as lower limit is set as 20%RH, returning stagnant setting value is 0.5%RH.When measured value is less than 20% RH, start humidification apparatus, when measured value reaches 20.5%RH, stop humidification apparatus, in the time that measured value drops to 20%RH again, start humidification again.Upper limit control: if upper limit set value is 30%RH, returning stagnant setting value is 0.5%RH.When humidity is greater than 30%RH, start dehumidification equipment, when humidity reaches 29.5%RH, stop dehumidifying, while rising to 30%RH, start again to dehumidify.
In the structure shown in Fig. 2, Temperature and Humidity Control loop is in parallel with the major loop of control circuit by circuit breaker Q F2, and the person of re-using gets involved, and while use, disconnects.
