Abstract
The invention discloses a safety protection system for a centrally installed switchgear; the safety protection system comprises a cabinet door which is provided with a travel switch; and the travel switch is connected with electrical equipment arranged in the centrally installed switchgear in series. As the centrally installed switchgear adopts the technical scheme, when the cabinet door is in an open state, the travel switch is off, a conducting loop can not be formed in the centrally installed switchgear, power can not be supplied, and the accidents can be prevented.
Description
Technical field
The present invention relates to a kind of parts of middle-placed switch cabinet, specifically a kind of middle-placed switch cabinet security protection system.
Background technology
Middle-placed switch cabinet, full name are metal armouring middle disposed withdrawn type switchgear, are mainly used in the distribution that is subjected to electric power transmission, industrial and mineral enterprises and institutions of power transmission, electric power system secondary substation of power plant, medium and small generator and starting of Large-scale High-Pressure motor etc.Middle-placed switch cabinet belongs to high voltage distribution installation, therefore will carry out security protection work.In prior art, just filling an electromagnetic lock on the middle-placed switch cabinet back door protects, namely only have when power failure just can open the work such as the cabinet door overhauls, do not have a power failure and to open the cabinet door, can power transmission but just but do not consider in situation that Men Wei shuts, if Men Wei shuts with regard to power transmission, easily cause the accident.
Summary of the invention
The object of the invention is to: for the problem of above-mentioned existence, provide a kind of middle-placed switch cabinet, can't power transmission in the situation that do not close the door.
The present invention is achieved through the following technical solutions:
A kind of middle-placed switch cabinet security protection system comprises cabinet and cabinet door, and cabinet and cabinet door junction are provided with travel switch, and in the normally opened contact of described travel switch and middle-placed switch cabinet, electric equipment and power supply are connected in series.
As the present invention further optimization scheme, described travel switch is connected in series between power supply and closing coil.
As the present invention further optimization scheme, described travel switch is connected in series between power supply and isolation handcart position latching electromagnet.
The present invention has following beneficial effect:
Due to middle-placed switch cabinet of the present invention, the place is provided with travel switch at the cabinet door, and in travel switch and middle-placed switch cabinet, electric equipment is connected in series, when cabinet door place and opening, travel switch disconnects, and can't form the conducting loop in middle-placed switch cabinet, also just can't power transmission, the generation of Accident prevention.
Description of drawings
Fig. 1 is middle-placed switch cabinet security protection system schematic diagram.
Fig. 2 is the circuit theory diagrams of embodiment 1.
Fig. 3 is the circuit theory diagrams of embodiment 2.
Fig. 4 is the middle-placed switch cabinet structural representation.
Embodiment
As shown in Figure 1, a kind of middle-placed switch cabinet security protection system comprises cabinet door 2, and 2 places are provided with travel switch 1 at the cabinet door, and travel switch 1 is connected in series with the interior electric equipment of middle-placed switch cabinet.
As shown in Figure 2, in incoming line cabinet, travel switch is connected between power supply and closing coil, and when the cabinet door was in opening, travel switch disconnected, and can't form the conducting loop, and closing coil can't be worked, also just can't power transmission.
As shown in Figure 3, in feed isolating cabinet, travel switch is connected between power supply and isolation handcart position latching electromagnet, when the cabinet door is in opening be, travel switch disconnects, and can't form the conducting loop, electromagnet can't be worked, and the isolation handcart can't move, also just can't power transmission.
