Abstract
The utility model relates to a lead-in detection device for a transformer. The lead-in detection device comprises a sensor and a pull rod in threaded connection with the sensor, wherein a rain-proof shield is arranged at the left end of the pull rod; a sleeve is arranged on the outer side of the joint between the sensor and the pull rod; a bleeding port is formed in the middle of the outer side of the sleeve and close to the joint between the sensor and the pull rod; a plastic guide part, a primary sealing piece, a secondary sealing piece and a tertiary sealing piece are sequentially arranged between the left end of the sleeve and the pull rod from the right to the left; a flange is arranged at the right end of the sleeve; the right end of the sensor extends into a through-hole in the center of the flange; and the joint between the flange and the sleeve is sealed by a seal ring. The utility model has the benefits that the length of the pull rod is adjustable and the position of the sensor can be changed; the sensor can be vertically and accurately positioned through the guide part and can not incline; and the pull rod exposed out of the sleeve can achieve precise length measurement after being demarcated, so that coordinate positioning of the sensor can be realized.
Description
Technical field
The utility model relates to a kind of transformer introducing-type pick-up unit.
Background technology
The transformer of electric system refers generally to generating end step-up transformer; Its main member is winding, iron core, fuel tank, transformer oil, insulation system; For guaranteeing the whole normal operation of transformer; Need above-mentioned parts are detected, the fuel outlet valve doorway detection commonly used that wherein is installed on tank surface is an on-line monitoring, promptly keeps charged and continues to detect down; And the on-line monitoring of electric signal adopts fixed sensor to monitor at present, the situation that the improper just needs of length design and install again often occurs; And reasonably do not use and operation instructions; Lean on experience or instruction decision fully, poor practicability, portable poor.
The utility model content
The purpose of the utility model provides a kind of transformer introducing-type pick-up unit, to overcome the above-mentioned deficiency that present prior art exists.
The purpose of the utility model is to realize through following technical scheme:
A kind of transformer introducing-type pick-up unit; Comprise sensor and with the pull bar of sensor through being threaded; The left end of said pull bar is provided with rain cover, and the outside, junction of sensor and pull bar is provided with sleeve, and the middle part in the sleeve outside is provided with bleeder port near the junction of sensor and pull bar; Set gradually plastic guides, primary seal spare, secondary seal and three grades of seals between the left end of sleeve and the pull bar from right to left; The right-hand member of sleeve is provided with flange, and the right-hand member of sensor stretches in the through hole of flange center, and the junction of flange and sleeve is through the O-ring seal sealing.
The beneficial effect of the utility model is:
1, pull bar adjustable length, sensing station can be changed;
2, the vertical accurately location of sensor can be guaranteed through guide, inclination can be do not produced;
3, pull bar is outside exposed at sleeve, but accurate measuring length after the demarcation realizes the sensor coordinates location;
4, through three grades of sealings, guarantee the sealing between pull bar and sleeve slide construction, satisfy leakproof demand at the insulating oil of fortune transformer online monitoring.
Description of drawings
According to accompanying drawing the utility model is done further explain below.
Fig. 1 is the cut-open view of the described transformer introducing-type of the utility model embodiment pick-up unit;
Fig. 2 is the side view of the described transformer introducing-type of the utility model embodiment pick-up unit.
Among the figure:
1, sensor; 2, pull bar; 3, rain cover; 4, sleeve; 5, bleeder port; 6, plastic guides; 7, primary seal spare; 8, secondary seal; 9, three grades of seals; 10, flange; 11, O-ring seal.
Embodiment
Shown in Fig. 1-2; The described a kind of transformer introducing-type pick-up unit of the utility model embodiment; Comprise sensor 1 and with the pull bar 2 of sensor 1 through being threaded; The left end of said pull bar 2 is provided with rain cover 3, and sensor 1 is provided with sleeve 4 with the outside, junction of pull bar 2, and the middle part in sleeve 4 outsides is provided with bleeder port 5 near the junction of sensor 1 and pull bar 2; Set gradually plastic guides 6, primary seal spare 7, secondary seal 8 and three grades of seals 9 between the left end of sleeve 4 and the pull bar 2 from right to left; The right-hand member of sleeve 4 is provided with flange 10, and the right-hand member of sensor 1 stretches in the through hole at flange 10 centers, and flange 10 seals through O-ring seal 11 with the junction of sleeve 4.
Sensor 1 is connected with pull bar 2 through screw thread, and the two seals; Pull bar 2 is a hollow structure, draws concentric cable from sensor 1 end, at pull bar 2 ends from drawing with the pull bar 2 vertical ports of drawing; Flange 10 is fixed on the transformer fuel outlet valve, and is fixing through 11 O-ring seals and sleeve 4; Bleeder port 5 is welded on the sleeve 4, release jacket coating air when pull bar 2 drives the sensor slip; Plastic guides 6 guarantees to combine closely between pull bar 2 and the sleeve 4, can not produce sensor perturbations because of the slip of pull bar 2; Primary seal spare 7, secondary seal 8 and three grades of seals 9 guarantee that pull bar 2 structures can not produce oil leakage phenomenon in sleeve 4 outer ends.
During concrete the use, withdraw pull bar 2 to rearmost end, on the transformer fuel outlet valve, fix flange 10; After opening bleeder port 5, open fuel outlet valve, transformer oil charges between sensor 2 and the sleeve 4 through fuel outlet valve; , bleeder port 5 representes that gas put sealing bleeder port 5 when having transformer oil to flow out; Leave standstill after the cleaning bleeder port 5 and be no less than half an hour, the sealing effectiveness of check sleeve 4 and bleeder port 5; According to the length requirement of design or experiment measuring, accurately adjust the length of pull bar 2, realize the accurate location of sensor 1; When needs adjustment sensor 1 position, change pull bar 2 length of exposing outside sleeve 4 and accurately adjust.
The utility model is not limited to above-mentioned preferred forms; Anyone can draw other various forms of products under the enlightenment of the utility model; No matter but on its shape or structure, do any variation; Every have identical with a application or akin technical scheme, all drops within the protection domain of the utility model.
