Abstract
The utility model belongs to a cabinet door switch detection device of an electric control cabinet, which is mainly used for safety protection of electric shock prevention of the electric control cabinet. The cabinet door switch detection device is formed by a detection element and a movement protection element, and is characterized in that the detection element is formed by one or more than one detection switch connected in series, and a maintenance switch connected with a travel switch in parallel; the detection switch is mounted on a cabinet door of the electric control cabinet; and the movement protection element is a tripping mechanism for controlling a power supply of the control cabinet to be on and off and is connected in a loop of the detection element in series. According to the cabinet door switch detection device disclosed by the utility model, opening and closing positions of the door of the electric control cabinet are detected to realize the forced safety requirements on the electric control cabinet in national standards.
Description
Technical field
The utility model is the detection control apparatus that belongs to electrical control cabinet cabinet door opening and closing state, is particularly useful for the safeguard protection of Electrical Control of Machinery Tools cabinet.
Background technology
Usually need to carry out Detection ﹠ Controling to the cabinet door opening and closing state of electrical control cabinet in prior art; present operation technique defectiveness; take the electrical control cabinet of lathe as example; the field of machine tool control cabinet safeguard protection at present; be generally tripping mechanism and get electric rear disconnection switch board power supply, namely when the cabinet door being detected and open, tripping mechanism gets electric; the disconnecting external power supply is connected with electrical control cabinet, to reach the purpose of protection.If pick-up unit and control protective unit electrical breaks, tripping mechanism can't get electric, namely can not disconnect the switch board power supply, does not reach the purpose of safeguard protection but in this manner.
Summary of the invention
The purpose of this utility model is for design defect in prior art, improves mentality of designing, make tripping mechanism with good conditionsi electric or outage, and keeping under original function, make up defective of the prior art.
The said electrical control cabinet cabinet of the utility model door switch pick-up unit is comprised of detecting element and action protection element.Detecting element is that one or more detector switch is connected in series, and a service switch composition that is in parallel with detector switch, and service switch is in normally open when normal operation, and detector switch is placed on electrical control cabinet cabinet door; The action protection element is for controlling the tripping mechanism of electrical control cabinet on/off, and tripping mechanism is connected in the loop of detecting element.
The said electrical control cabinet cabinet of the utility model door switch pick-up unit, when the electrical control cabinet door is opened, detector switch disconnects, cause detecting element loop dead electricity, the power supply of tripping mechanism cutting-off controlling cabinet enters into the personal security of switch board, when the maintenance personal need to use power supply to keep in repair with guarantee, the service switch that manually closes gets final product to get electric detection and the maintenance of carrying out switch board.
Description of drawings
Accompanying drawing 1: schematic diagram is controlled in the door opening electrical outage protection.
Embodiment
Accompanying drawing 1 is the said electrical control cabinet cabinet of the utility model door switch pick-up unit schematic diagram.Formed by detecting element and action protection element.Detector switch 3 in detecting element is placed on the switch board door, and each detector switch 3 is connected in series, and service switch 2 is connected in parallel with detector switch 3; The action protection element is the tripping mechanism 1 of electrical control cabinet general supply, and tripping mechanism 1 is connected in the loop of detecting element.
When the electrical control cabinet door was normally closed, detector switch 3 was normally off, and tripping mechanism 1 gets electric, keeps normal operating condition; When having any one switch board door to open, one of them detector switch 3 is transformed into normally open from normally off, during simultaneously because of normal operation, service switch also is in normally open, detecting element this moment loop disconnects, tripping mechanism 1 is under-voltage condition, the total power switch 4 that is connected with external power source is cut off in tripping mechanism 1 action, reaches electrical control cabinet 5 outage purposes.When needs are having when keeping in repair under electricity condition, manually service switch 2 is converted to normally off, make tripping mechanism 1 electric, at this moment detector switch 3 no matter in Chang Kai or normally off, does not affect the work of tripping mechanism 1, making it to arrive maintenance has electric purpose.
The said electrical control cabinet cabinet of the utility model door switch pick-up unit, wherein said detector switch can be travel switch, or approach switch, or optoelectronic switch.
From the formation of the said electrical control cabinet cabinet of the utility model door switch pick-up unit and principle as seen, the protection that is applied to various switch boards that this device can be safe and reliable reaches the purpose of door opening electrical outage.
