Abstract
The utility model discloses a strong-current blocking electric control system of a grounding switch. The system includes a high-voltage electrified sensor arranged on a side of a cable. The high-voltage electrified sensor connects with an electrified display having a blocking starting function. The electrified display connects with a grounding strong current blocking module. The grounding strong current blocking module connects with a latching electromagnet conducting a switching function. The latching electromagnet is disposed in a position of an operating hole of the grounding switch. A 10 kV looped network switch cabinet equipped with the strong-current blocking electric control system of the grounding switch can guarantees the personal safety of maintenance workers through the grounding switch, but also avoid running faults of short circuit of the grounding connection of a high-voltage conductor caused by an error operation of switching in the grounding switch of an operator.
Description
Technical field
The utility model relates to a kind of earthed switch forceful electric power locking electric control system.
Background technology
Personal safety in order to guarantee to overhaul, general 10kV loop-network switch cabinet cable side all disposes earthed switch when implementing electric maintenance, has only the combined floodgate earthed switch could open the protective door in cable storehouse.When earthed switch assurance personal safety can be set, also brought the potential safety hazard in the operation, under the charged situation of cable,, will cause the security of operation accident of the charged direct shorted to earth of conductor if the operations staff does not have attention and the false switching earthed switch.
The utility model content
For solving under the charged situation of cable side; Thereby operations staff's mistake splice grafting ground switch causes the problem of the direct shorted to earth of energized conductor; The utility model is opened and is proposed a kind of 10kV earthed switch forceful electric power locking electric control system; Have through the induction cable side not have the 10kV forceful electric power and press, determine whether starting earthed switch operation locking electromagnet, thereby realize whether earthed switch being implemented forceful electric power operation locking function.
The utility model is that the technical scheme that its technical problem of solution is adopted is,
Earthed switch forceful electric power locking electric control system; It is characterized in that; Include the electrification in high voltage transducer that is arranged at cable side, the electrification display that said electrification in high voltage transducer and has locking startup function is connected, and electrification display is connected with ground connection forceful electric power lock modules; Ground connection forceful electric power lock modules is connected with the latching electromagnet of carrying out switching function, and said latching electromagnet is located at earthed switch handle hole place.
The advantage of the utility model is; The 10kV loop-network switch cabinet that has disposed this earthed switch forceful electric power locking electric control system both can ensure maintainer's personal safety through earthed switch, can evade the operation troubles that causes having the direct shorted to earth of high-voltage conductor because of operations staff's false switching earthed switch again.
Description of drawings
Fig. 1 is the structural representation of the earthed switch forceful electric power locking electric control system of the utility model proposition.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand with effect and understand, below in conjunction with illustrating and specific embodiment, further set forth the utility model.
The earthed switch forceful electric power locking electric control system that the utility model proposes includes the electrification in high voltage transducer that is arranged at cable side; The electrification display that said electrification in high voltage transducer and has locking startup function is connected; Electrification display is connected with ground connection forceful electric power lock modules; Ground connection forceful electric power lock modules is connected with the latching electromagnet of carrying out switching function, and said latching electromagnet is located at earthed switch handle hole place.
Embodiment:
Referring to Fig. 1, in cable side three-phase thimble tube electrification in high voltage transducer L1, L2, L3 are set, be responsible for the induction cable side by this transducer and whether have high voltage;
At the cabinet correct position a kind of electrification display GSN that locking starts function that has is set, is responsible for the information that the cable side transducer sends is judged by it, and determines whether sending the locking log-on message according to judged result;
A kind of ground connection forceful electric power lock modules BSN that sends the enforcement blocking function that possesses is set on cabinet instrument door face board, the locking log-on message that it sends according to electrification display, the dry contact that action is inner is seen the startup power supply off to latching electromagnet;
Settle a miniaturization latching electromagnet Y1 at earthed switch handle hole correct position, it is responsible for locking earthed switch operating function as the final executor of forceful electric power locking.
The 10kV loop-network switch cabinet that has disposed this earthed switch forceful electric power locking electric control system both can ensure maintainer's personal safety through earthed switch, can evade the operation troubles that causes having the direct shorted to earth of high-voltage conductor because of operations staff's false switching earthed switch again.
More than show and described the advantage of basic principle, principal character and the utility model of the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; The utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection range to be defined by appending claims and equivalent thereof.
