Accompanying drawing explanation
Fig. 1 is the circuit diagram of dry-type transformer safety system in the utility model.
Detailed description of the invention
For the ease of understanding the utility model, below with reference to relevant drawings, the utility model is described more fully.Preferred embodiment of the present utility model is given in accompanying drawing.But the utility model can realize in many different forms, is not limited to embodiment described herein.On the contrary, provide the object of these embodiments be make the understanding of disclosure of the present utility model more comprehensively thorough.
It should be noted that, when element is called as " being fixed on " another element, directly can there is element placed in the middle in it on another element or also.When an element is considered to " connection " another element, it can be directly connected to another element or may there is centering elements simultaneously.Term as used herein " vertical ", " level ", "left", "right" and similar statement are just for illustrative purposes.
Unless otherwise defined, all technology used herein and scientific terminology are identical with belonging to the implication that those skilled in the art of the present utility model understand usually.The object of the term used in manual of the present utility model herein just in order to describe specific embodiment, is not intended to be restriction the utility model.Term as used herein " and/or " comprise arbitrary and all combinations of one or more relevant Listed Items.
Please refer to Fig. 1, in the utility model one preferred embodiment, dry-type transformer comprises iron core (not shown), be set around coil (not shown) on iron core and protection system 10.Coil comprises two or more winding.Wherein, the winding connecing power supply is called primary coil (hereinafter referred to as primary side), and remaining winding is called time group coil (hereinafter referred to as secondary side).In this specific embodiment, the primary side of dry-type transformer is high-pressure side, and secondary side is low-pressure side.The electromagnetic lock 13 that protection system 10 comprises gauge tap 11 and is electrically connected with gauge tap 11.Wherein, gauge tap 11 is electrically connected between Circuit Fault on Secondary Transformer and electromagnetic lock 13, for the low tension signal of receiving transformer to control unblanking and locking of electromagnetic lock 13, thus the mode of operation of control transformer.Wherein, when electromagnetic lock 13 locking, transformer is in non-operating state, and namely operating personnel can not to operate; When electromagnetic lock 13 is unblanked, transformer is in operable state, and namely operating personnel can open operate.
Particularly, gauge tap 11 comprises control part 110 and controlled portion 112.The secondary side that control part 110 is electrically connected on transformer controls the opening and closing in controlled portion 112 according to the low-voltage signal received.The one end in controlled portion 112 is electrically connected with one end of electromagnetic lock 13, the other end external power supply in controlled portion 112.
In this specific embodiment, gauge tap 11 is auxiliary reclay, and dry-type transformer is dry-type three-phase transformer, and above-mentioned control part 110 is specifically respectively coil and constant close contact with controlled portion 112.One end D1 of coil is electrically connected in any phase in Three-Phase Transformer, and the other end D2 of coil is electrically connected on zero line and forms electric loop.One end of constant close contact is electrically connected on electromagnetic lock 13, and the other end of constant close contact is electrically connected on external power supply.
One end of electromagnetic lock 13 is electrically connected with controlled portion 112, and the other end of electromagnetic lock 13 is electrically connected with external power supply V1.Electromagnetic lock 13, controlled portion 112 and external power supply V1 together form a series-fed loop.In this specific embodiment, electromagnetic lock 13 comprise induction coil 130, tutorial light 132, console switch 134, lock frame (not shown), with lock the dead bolt (not shown) that frame coordinates and the spring (not shown) tutorial light be connected with dead bolt.
Induction coil 130 and controlled portion 112 are electrically connected, and open and locking relative to lock frame for controlling dead bolt.Particularly, when induction coil 130 obtains electric, induction coil 130 adsorbs dead bolt, and dead bolt is separated and Compress Spring with lock frame, to remove the lock-out state of electromagnetic lock 13; When induction coil 130 dead electricity, induction coil 130 discharges dead bolt, makes dead bolt reinsert in lock frame under the effect of spring power, to lock electromagnetic lock 13.
Console switch 134 is connected with induction coil 130, obtains electric and dead electricity, to control opening and locking of electromagnetic lock 13 for controlling induction coil 130 according to the operation of operating personnel.Wherein, console switch 134 is for being arranged at the press button on electromagnetic lock 13.In some other embodiment, console switch 134 also can be contact witch, in this no limit.
Tutorial light 132 is in parallel with induction coil 130, whether is in mode of operation for indicating current transformer when console switch 134 closes.Particularly, when console switch 134 closes, tutorial light 132 lamp is bright, namely indicates current transformer to be operable state; And when tutorial light 132 extinguishes, then indicate current transformer to be in non-operating state.
In this specific embodiment, console switch 134 is series between one end of induction coil 130 and the one end in controlled portion 112, and the other end of induction coil 130 is electrically connected with external power supply V1, and the other end of external power supply V1 is electrically connected with the other end in controlled portion 112.So, controlled portion 112, induction coil 130 and external power supply V1 connect formation current supply circuit jointly.
When dry-type transformer is for normally working; the coil of auxiliary reclay obtains electric adhesive; constant close contact disconnects; induction coil 130 dead electricity also makes dead bolt at next straight cutting of effect of spring power in locking in frame; tutorial light 132 is in extinguishing always, and to indicate current transformer to be in non-operating state, now electromagnetic lock 13 quits work because of non-transformer and keeps forced blocking state; the door of transformer can not open maintenance blocking, thus reaches the effect of protection.When dry-type transformer is not charged, the coil losing electricity of auxiliary reclay disconnects, constant close contact closes, and when operating personnel's push switch 134 makes it closed, tutorial light 132 lamp is bright, instruction current transformer is in mode of operation, induction coil 130 obtains Electro Sorb dead bolt, and dead bolt is separated and Compress Spring with lock frame, now the normal work release of electromagnetic lock 13, the door removing locked signal of transformer, can carry out equipment operating.
The above embodiment only have expressed several embodiment of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make multiple distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
