The utility model solves the problems of common appliance being transferred into safety type control loop through intrinsic safety type loop, which is suitable for promotion of appliance in coal well gas environment, improves coal under well appliance safety and employment range and lowers manufacture cost.

Description

A kind of safety-type isolated gate controller

Technical field:

The utility model relates to the technical field of mining electrical equipment, a kind of specifically safety-type isolated gate controller, particularly its circuit connection structure.

Background technology:

The essential safe type control loop that existing colliery electrical equipment all adopts the upright original paper of single loop list to be combined into, it is applicable under the coal mine with explosion hazards such as methane, existing circuit structure is more aging, security performance is lower, manufacturing cost is higher, so still need prior art is further improved.

The utility model content:

The purpose of this utility model is to provide a kind of safety-type isolated gate controller, its integrated circuit is rational in infrastructure, utilizes electronic circuit to realize AC voltage conversion, has reduced manufacturing cost, effectively dwindle the volume of product, overcome the shortcoming and defect that exists in the prior art.

To achieve these goals, the technical solution of the utility model is: a kind of safety-type isolated gate controller, it mainly comprises power circuit, is characterised in that: the output of described power circuit is connected with the input in intrinsic safety loop, and described intrinsic safety loop is formed in parallel by at least 10 photodiodes.

The utility model discloses a kind of safety-type isolated gate controller, solved general electrical equipment and converted essential safety-type control loop to by this controller multiloop, can adapt to the popularization that the coal mine gas environment uses general electrical equipment, improve the fail safe and the scope of application of electrical equipment under the coal mine, reduced manufacturing cost simultaneously.

Description of drawings:

Fig. 1 is circuit theory diagrams of the present utility model.

Embodiment:

With reference to the accompanying drawings, the utility model further is described

The utility model is a kind of safety-type isolated gate controller, as Fig. 1 as shown in it, it mainly comprises power circuit 1, be characterised in that: the output of described power circuit 1 is connected with the input in intrinsic safety loop 2, described intrinsic safety loop 2 is formed in parallel by at least 10 photodiodes, photodiode 5 input ends are provided with two feeler lines, and wherein a feeler line place is connected with a resistance 3, and another root feeler line place is provided with terminals 4.

This controller is to adopt newly designed circuit of SSR and technology in the world, the intrinsic safety electric current of input constant current, it is that media comes transmission of electric signals with light, when input adds the signal of telecommunication, light-emitting diode emits beam, and light-receiving device is accepted just to produce photoelectric current behind the light and flowed out from output, thus the conversion that realizes " electricity-light-", input and output have been realized isolation fully, are the usefulness as intrinsic safety loop and the loop coupling of non-intrinsic safety.

In the specific implementation, this controller uses at " starter " and goes up the usefulness that is converted into the intrinsic safety loop as non-intrinsic safety loop, " starter " a large amount of use only used as switch in colliery and coal mine machinery, with explosion-proof air compressor machine is example: no matter be that air compressor machine, motor or starter can only use signal lamp when sending fault in the past in the starter fault shows, demonstrate from green light and be converted to red light, because of " this controller " is multiloop, can link to each other with " electromagnetism starting intelligent controller " after using this controller, finish human-computer dialogue, fault, position.Situations such as time can solve at the interface, have saved the correct formulation of maintenance time and abort situation, also are convenient to confirmation of responsibility.
