Abstract
The present utility model discloses a looped network cabinet safety device and relates to the looped network cabinet equipment technical field. The device comprises a looped network cabinet, an operating hole arranged on the looped network cabinet, an air pressure detection device and a latch-down baffle. One end of the latch-down baffle is hinged to the inner side wall of the looped network cabinet, the other end is arranged on the lower end of the operating hole, an electromagnet is fixed on the inner side wall of the looped network cabinet, which is on the upper end of the operating hole, a power supply is fixed on the inner side wall of the looped network cabinet, the air pressure detection device and the electromagnet are respectively and electrically connected with the power supply, and the air pressure detection device is electrically connected with the electromagnet. In the device, a pressure sensor of the air pressure detection device is adopted to detect interior air pressure of the looped network cabinet, a controller is adopted to control the power supply and supply power for the electromagnet, the electromagnet is powered on to generate electromagnetic force to attract the latch-down baffle, an open end of the latch-sown baffle is rotated around a hinged end and is used for sealing the operating hole directly, thus operating personnel can be prevented from operating the looped network cabinet under the low air pressure state, and safety accidents can be avoided.
Description
Technical field
The utility model relates to a kind of looped network cabinet equipment technical field, relates in particular to a kind of ring main unit safety device.
Background technology
Ring main unit is meant the loading switch cabinet that is applied in the annular electric supply network; It is that one group of high voltage switchgear is assemblied in the assembly unit compartment electric equipment of being formed in the steel sheet metal cabinet, and on-load switch has been adopted or by unit equipment that on-load switch and fuse constituted in its core; It has simple in structure, volume is little, price is low, can improve advantages such as power supply performance and power supply reliability, be widely used in the supply network in places such as Urban House sub-district, skyscraper, large public building, factory and enterprise.
At present, existing ring main unit is provided with gas-insulated mechanism more, promptly is filled with the insulating properties gas of certain pressure at ring main unit, with insulating capacity and the arc extinguishing ability that guarantees whole ring main unit; The insulating properties gas that existing ring main unit adopted can comprise air or SF6 gas.Atmospheric pressure value in the ring main unit directly affects the insulating capacity and the arc extinguishing ability of whole ring main unit; (safety value is meant if ring main unit internal gas pressure value is when being lower than this value when ring main unit internal gas pressure value is lower than safety value; Then just there is security risk in this ring main unit); The insulating capacity of this ring main unit and arc extinguishing ability can reduce greatly, if this moment, operating personnel operated ring main unit, then can have great security risk.Existing ring main unit can only be confirmed whether safety of ring main unit internal gas pressure value through operating personnel's active detecting; Low pressure automatic blocking function is not set; If, just probably cause the generation of security incident when ring main unit internal gas pressure value is lower than safety value so operating personnel operate ring main unit.
The utility model content
To the weak point that above-mentioned prior art exists, the purpose of the utility model is to provide a kind of ring main unit safety device, and this ring main unit can prevent effectively that operating personnel from operating ring main unit under low pressure, avoided the generation of security incident.
The purpose of the utility model realizes through following technical proposals:
A kind of ring main unit safety device comprises ring main unit and is located at the handle hole on the ring main unit, also comprises air pressure sniffer and latch-down baffle; Latch-down baffle one end is articulated on the madial wall of ring main unit; The other end is positioned at the lower end of handle hole, is fixed with electromagnet on the madial wall on ring main unit is positioned at handle hole, also is fixed with power supply on the madial wall of ring main unit; Said air pressure sniffer, electromagnet are electrically connected with power supply respectively, and the air pressure sniffer is electrically connected with electromagnet.
In order to realize the utility model better, said air pressure sniffer comprises pressure sensor and controller.
Further, said latch-down baffle is formed by iron.
The utility model is compared than prior art, has the following advantages and beneficial effect:
The utility model can be surveyed the air pressure inside of ring main unit through the pressure sensor in the air pressure sniffer; And be the electromagnet power supply through controller control power supply; Electromagnet energising back produces the electromagnetic attracting force latch-down baffle; The latch-down baffle open end rotates around hinged end also directly seals handle hole, thereby realizes preventing that operating personnel from operating ring main unit, avoided the generation of security incident under the low pressure state.

Wherein, the pairing name of the Reference numeral in the accompanying drawing is called:
The 1-ring main unit, 2-handle hole, 3-latch-down baffle, 4-air pressure sniffer, 5-power supply, 6-electromagnet.
Embodiment
Below in conjunction with embodiment the utility model is done to specify further, but the execution mode of the utility model is not limited thereto.
Embodiment
As shown in Figure 1, a kind of ring main unit safety device comprises ring main unit 1 and is located at the handle hole 2 on the ring main unit 1, also comprises air pressure sniffer 4 and latch-down baffle 3, and the latch-down baffle of present embodiment 3 is formed by iron.Latch-down baffle 3 one ends are articulated on the madial wall of ring main unit 1, and the other end is positioned at the lower end of handle hole 2; Be positioned at ring main unit 1 on the madial wall of handle hole 2 upper ends and be fixed with electromagnet 6, also be fixed with power supply 5 on the madial wall of ring main unit 1, said air pressure sniffer 4, electromagnet 6 are electrically connected with power supply 5 respectively.The air pressure sniffer 4 of present embodiment comprises pressure sensor and controller, and controller is electrically connected with electromagnet 6.
In sum, just can realize the utility model preferably.
