Abstract
The invention discloses a grounded switch blade anti-misoperation indicating device which comprises an alternating current power source (1), a live display locking device (2), a locking electromagnet (3) arranged on a grounded switch blade, and an alarm device. The alternating current power source (1) is sequentially connected with the live display locking device (2), the locking electromagnet (3) and the alarm device in series to form a loop (4). The live display locking device (2) is used for controlling the electricity obtaining condition of the locking electromagnet (3) according to the electricity obtaining condition of the loop. The alarm device is used for visually and accurately prompting whether the locking electromagnet (3) obtains electricity or not, and therefore whether the grounded switch blade is allowed to be operated or not is prompted.
Description
Technical field
The present invention relates to a kind of earthing switch blade anti-misoperation indicating device.
Background technology
Constantly update with power equipment along with electric power enterprise constantly develops; device category is various; the methods of operation are also along with variation; major part personnel all can not to the operation of all equipment or simple failure condition very familiar, so just often there will be the situation of some misoperations or damage equipment at work.In the operation of power failure, power transmission, the operation of switch-cabinet grounding plug-in strip is essential, because number of operations is various, earthing switch blade breaks down unavoidable, and the repairing work therefore brought adds the operating efficiency that many workloads also greatly reduce operations staff not only to we maintainer.
Summary of the invention
The invention provides a kind of earthing switch blade anti-misoperation indicating device, it can intuitively find out earthing switch blade latching electromagnet whether electric, can earthing switch blade operate, and avoids unnecessary mechanical damage.
Present invention employs following technical scheme: a kind of earthing switch blade anti-misoperation indicating device, it is characterized in that it comprises AC power, band point display locking device, the latching electromagnet that earthing switch blade is provided with and warning device, AC power puts a display locking device with band successively, latching electromagnet and warning device are concatenated into loop, described band point display locking device be used for according to loop electric situation control latching electromagnet electric situation, described warning device be used for pointing out latching electromagnet whether intuitively and accurately electric, thus whether prompting allows operatively cutter.
Described AC power is the AC power of 220V.Described band point display locking device is set to high pressure belt point display locking device.Described warning device is set to alarm lamp combination, and alarm lamp combination comprises two alarm lamps, the connection parallel with one another of two alarm lamps.
The present invention has following beneficial effect: after have employed following technical scheme, the present invention includes AC power, band point display locking device, the latching electromagnet that earthing switch blade is provided with and warning device, AC power puts a display locking device with band successively, latching electromagnet and warning device are concatenated into loop, described band point display locking device be used for according to loop electric situation control latching electromagnet electric situation, described warning device be used for pointing out latching electromagnet whether intuitively and accurately electric, thus whether prompting allows operatively cutter, can intuitively find out like this earthing switch blade latching electromagnet whether electric, can earthing switch blade operate, avoid unnecessary mechanical damage, can effectively reduce earthing switch blade when latching electromagnet must not electricity, misoperation damages the situation of internal structure, structure of the present invention is simple in addition, can transform at short notice.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
In FIG, the invention provides a kind of earthing switch blade anti-misoperation indicating device, it comprises AC power 1, band point display locking device 2, the latching electromagnet 3 that earthing switch blade is provided with and warning device, AC power 1 is the AC power of 220V, AC power 1 puts a display locking device 2 with band successively, latching electromagnet 3 and warning device are concatenated into loop 4, described band point display locking device 2 is set to high pressure belt point display locking device, described band point display locking device 2 for according to loop electric situation control latching electromagnet 3 electric situation, described warning device be used for pointing out intuitively and accurately latching electromagnet 3 whether electric, thus whether prompting allows operatively cutter, described warning device is set to alarm lamp combination, alarm lamp combination comprises two alarm lamps 5, the connection parallel with one another of two alarm lamps 5, when there is charged situation in loop, band point display locking device 2 disconnects, latching electromagnet 3 is not charged, two alarm lamps 5 extinguish, operatively cutter can not be allowed, when there is powering-off state in loop, band point display locking device 2 closes, latching electromagnet 3 is charged, at least one alarm lamp 5 is bright, operatively cutter can be allowed, effectively protect internal structure.
