Kind light, quiet and service life length switch element, by switch element and front end sensing unit and rear end execution unit it
Between by the unified integration of control unit, the process of automatic switch is realized to heating process by the way of vulnerabilities scan forceful electric power,
So as to improve the increasingly automated of heating unit in deicing or snow melting equipment.
The purpose of this utility model is achieved through the following technical solutions：
A kind of switch element for automatic computer heating control, including electronic programmable controller and at least two solid-state relays
Device, the signal output terminal of electronic programmable controller is connected as its offer with the control signal of two solid-state relays respectively
Switch controlling signal, the main circuit terminal of two solid-state relays is respectively connected to the wherein two-phase of three phase mains, solid-state relay
Circuit closure is triggered by photoelectricity or disconnects main circuit to realize the unlatching for powering to heating unit 380V three-phase triangular loads
Or disconnect.
In order to realize Automated condtrol, in addition to front end sensing part, the front end sensing part include ice and snow detector,
Atmosphere temperature transducer and surface temperature sensor, the ice and snow detector, atmosphere temperature transducer and surface temperature sensor
Access the corresponding pin of electronic programmable controller.
Compared with prior art, the utility model embodiment at least has advantages below：
The outdoor that the utility model switch element is particularly suitable for use under severe weather conditions is full-automatic or Semiautomatic heating system
System, it is adaptable to which those regard deicing or snow melting and cleaning roadblock as the place of essential safety measure, such as road；Bridge；
Concrete, pitch, brick, soil surface etc.；Building roof and gutter；The pavement lived with walking area；Airfield runway；Iron
Road；Sports ground；Warmhouse booth and outdoor agricultural etc..
Switch element is not similar to the electromechanical operation of magnet coil contactor, comparatively speaking, magnet coil contactor
Need to provide bigger operating current, service life is short and has very big noise when acting.Solid-state relay is light and handy, almost without
Noise and the constraint without service life.

Embodiment of the present utility model is described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning
Same or similar element or element with same or like function are represented to same or similar label eventually.Below by ginseng
The embodiment for examining accompanying drawing description is exemplary, it is intended to for explaining the utility model, and it is not intended that to the utility model
Limitation.
The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is the electrical structure schematic diagram of the utility model deicing or snow melting system.
As shown in figure 1, a kind of switch element for automatic computer heating control, including electronic programmable controller 2 and at least
The power input of two solid-state relays 1, the signal output terminal of electronic programmable controller 2 and two solid-state relays 1
It is connected as it and switch controlling signal is provided, the main circuit terminal of two solid-state relays 1 is respectively connected to wherein the two of three phase mains
Phase, solid-state relay triggers circuit closure by photoelectricity or disconnects main circuit and heating unit 380V three-phases triangle is born with realizing
Carry turning on or off for power supply.
Also include front end and sense part, the front end sensing part includes ice and snow detector 4, the and of atmosphere temperature transducer 3
