Abstract
The utility model relates to an electric safety protection device for tightly stopping an access door of a generator set, which comprises a switch cabinet and a control cabinet, wherein a controller is arranged in the control cabinet, the controller is connected with a tightly stopping loop, and micro-motion mechanisms of interlocking switches are arranged on the doors of the switch cabinet and the control cabinet; the normally closed contact of the interlock switch is connected in series in the emergency stop loop; the micro-motion mechanism is used for detecting the opening states of the doors of the switch cabinet and the control cabinet and sending an action signal to the normally closed contact when the door of the switch cabinet or the control cabinet is opened; the normally closed contact is opened after receiving the action signal, so that the emergency stop loop is invalid; and the controller controls to output a shutdown signal after detecting that the emergency stop loop is invalid. The utility model discloses can be after access door is opened automatic shutdown generating set, eliminated the potential safety hazard.
Description
Technical Field
The utility model relates to a generating set electrical safety technical field especially relates to an electrical safety protection device that generating set access door opening door tightly stopped.
Background
The protection level of the generator set box body is high, and absolute electrical safety is needed when the generator set is used and maintained. The access doors of the existing generator set switch cabinet and control cabinet only have door lock structures, and no reminding or protecting device is provided when the doors are opened. When the diesel generator set opens the door of the switch cabinet or the control cabinet in the running state, the rear-end equipment may be damaged, and even the personal injury of maintenance personnel may be caused.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that an electric safety device that generating set access door opened the door and tightly stopped is provided, can close the generating set automatically after the access door was opened.
The utility model provides a technical scheme that its technical problem adopted is: the electric safety protection device for the open-door emergency stop of the access door of the generator set comprises a switch cabinet and a control cabinet, wherein a controller is arranged in the control cabinet, the controller is connected with an emergency stop loop, and micro-motion mechanisms of interlocking switches are arranged on the doors of the switch cabinet and the control cabinet; the normally closed contact of the interlock switch is connected in series in the emergency stop loop; the micro-motion mechanism is used for detecting the opening states of the doors of the switch cabinet and the control cabinet and sending an action signal to the normally closed contact when the door of the switch cabinet or the control cabinet is opened; the normally closed contact is opened after receiving the action signal, so that the emergency stop loop is invalid; and the controller controls to output a shutdown signal after detecting that the emergency stop loop is invalid.
The emergency stop loop comprises a plurality of emergency stop button normally closed contacts connected in series.
The controller adopts a Kemei IS-NTC-BB machine set control module.
Advantageous effects
Since the technical scheme is used, compared with the prior art, the utility model, have following advantage and positive effect: the utility model discloses a set up interlocking switch's micro-gap mechanism on cubical switchboard and control cabinet to in the tight loop that stops that inserts interlocking switch's normally closed contact and be connected with the controller, can touch tight loop work when interlocking switch's micro-gap mechanism triggers, make the controller send shutdown signal, realize overhauing the cabinet auto-stop generating set after opening the door, eliminate the potential safety hazard, protect personal safety.

Detailed Description
The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes and modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope of the appended claims.
The embodiment of the utility model relates to an electric safety protection device for tightly stopping an access door of a generator set, as shown in figure 1, comprising a switch cabinet and a control cabinet, wherein a controller 1 is arranged in the control cabinet, the controller 1 is connected with a tightly stopping loop 2, and micro-motion mechanisms of an interlocking switch 2S1 are arranged on the doors of the switch cabinet and the control cabinet; the normally closed contact of the interlock switch 2S1 is connected in series in the emergency stop loop 2; the micro-motion mechanism is used for detecting the opening states of the doors of the switch cabinet and the control cabinet and sending an action signal to the normally closed contact when the door of the switch cabinet or the control cabinet is opened; the normally closed contact is opened after receiving the action signal, so that the emergency stop loop 2 is invalid; and the controller 1 controls to output a shutdown signal after detecting that the emergency shutdown loop 2 is failed.
In the embodiment, the emergency stop loop 2 comprises a plurality of normally closed contacts of the emergency stop buttons 1S2 connected in series, and emergency stop of the generator set can be realized at each position by arranging the emergency stop buttons 1S2, so that personal safety is guaranteed.
The controller 1 in this embodiment employs a comma IS-NTC-BB unit control module that can be used in both stand-alone and parallel modes, and that IS equipped with a powerful image display device capable of operating intuitively. The control module has high functions and new standard performance, can automatically realize GCB closing, and can stop the engine through an external signal or a button press when all conditions are met.
The utility model discloses an increase the interlock switch that opens the door to in the tight loop that stops that inserts the interlock switch and be connected with the controller, can touch tight loop work when the interlock switch triggers, make the controller send stop signal, realize overhauing the cabinet and opening the door back auto-stop generating set, eliminate the potential safety hazard, protect personal safety.
Claims (3)
