Abstract
The utility model relates to an explosion-proof electric controller which is provided with an outer shell with a flame-proof cavity, wherein a control circuit board, a safety grid plate and a display screen, which are connected and assembled in turn, are arranged in the flame-proof cavity, and a cable leading-in component is arranged on one side of the outer shell. The controller is characterized in that an intrinsic safety type related device and a control device are arranged in the shell body, thereby greatly reducing the length of a connecting cable and the manufacturing cost, simultaneously extending the use range of the controller, enabling the controller to carry out the operations of controlling the switch and adjusting the parameter and the like in explosion hazardous areas, and having safe and reliable use.
Description
Technical field
The utility model belongs to the explosion-proof electrification technical field, is a kind of explosion-proof electrification controller.
Background technology
In technique known, the electrical control gear that is used for operations such as switch control and adjustment parameter is normally with control device and the partial installation of intrinsic safety type associate device, connect by cable therebetween, because intrinsic safety type associate device and control device distance of separation are far away, cause the cable line that connects long, therefore, not only consumptive material is many, the manufacturing cost height, and can not be used for explosion hazard area because of control device does not possess explosion prevention function.
The utility model content
The purpose of this utility model provides a kind of collection intrinsic safety type associate device and control device is an one, can implement the explosion-proof electrification controller of operations such as switch control and adjustment parameter at explosion hazard area.
Realize that the technical scheme that the purpose of this utility model is taked is: this controller has the shell of a band explosion-proof chamber, is provided with the control circuit board that assembles successively, safe screen and display screen in the explosion-proof chamber, and a side of shell is provided with cable and introduces member.
Described shell is made up of housing and case lid, and the two adopts flanged flameproof joint structure, and installs sealing gasket additional, is provided with at the sidepiece of housing that cable is introduced the hole and outwardly directed cable is introduced the member installing hole.
Described case lid is provided with observation window and display control panel.
Line between described safe screen and the display screen adopts and waters packing material structure.
Cable introducing place of described display screen adopts cable branch-off to water packing material structure.
It is T shape structure that described cable is introduced member, introduces the employing of member installing hole with cable and is threaded, and cable is introduced the member centre and is provided with the cable entrance hole.
The explosion-proof electrification controller of making according to such scheme, intrinsic safety type associate device and control device are arranged in the housing, significantly reduced the length of stube cable thus, and reduced manufacturing cost, widened the scope of application of controller simultaneously, make this controller can implement operations such as switch control and adjustment parameter at explosion hazard area, and safe and reliable.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1.
Embodiment
Referring to Fig. 1, explosion-proof electrification controller of the present utility model, shell with a band explosion-proof chamber, form by housing 1 and case lid 2, the two adopts the flanged flameproof joint structure, and install sealing gasket additional, sidepiece at housing 1 is provided with cable introducing hole 3 and outwardly directed cable introducing member installing hole 4, by screw thread cable is housed in the installing hole 4 and introduces member 5, it is T shape structure that this cable is introduced member 5, its centre is provided with the cable entrance hole, and case lid 2 is provided with observation window 6 and display control panel 7.Be provided with the circuit control panel 9, safe screen 10 and the display screen 8 that assemble successively in the explosion-proof chamber, circuit control panel 9 is connected with LCD display, line between safe screen 10 and the display screen 8 adopts and waters packing material structure, and cable introducing place 11 of display screen 8 adopts cable branch-off to water packing material structure.This controller is by the setting of safe screen 10, intrinsic safety type associate device and control device are installed in the same flame proof housing, and the whole flame-proof type structure that adopts, thereby can implement operations such as switch control and adjustment parameter at explosion hazard area, and significantly reduced the length of stube cable.
