Abstract
The utility model relates to a supplementary monitoring devices of transformer oil pillow oil level for to assist the monitoring with the transformer through the oil level of the conservator that allies oneself with the pipe and be connected, the oil level of supplementary monitoring devices of transformer oil pillow oil level in at least can the antithetical couplet managing carries out the engine oil level sensor that detects, the backstage monitored control system looks signal connection of sensor and transformer. The utility model discloses an engine oil level sensor who is connected with the backstage monitored control system of transformer can audio -visually read the oil level, still can really read the oil level by calibration fall to zero point of its self oil level index gauge when oil level in the conservator under to be convenient for to the conservator refuel with the control of oil drain process.
Description
Technical field
This utility model relates to a kind of conservator being connected transformator and carries out the device of oil level auxiliary monitoring.
Background technology
Transformator is the visual plant in power system, and its safe and stable operation is the important duty of operation maintenance personnel.Conservator is as one of the critical piece of transformator, and its effect is to accommodate certain transformer oil and expand with heat and contract with cold oil level in transformer body and compensate, to ensure that transformer body and associated components are among the insulation protection of transformer oil all the time.On-the-spot conservator major part all uses capsule structure, and the instruction of oil level is converted into lattice number by magnetic-type oil level indicator, then is compareed with temperature by oil level curve, sees that on-the-spot running temperature dative number the most quite observes oil level.
Scene is run, there is certain drawback in this kind of mode, one is that the position of magnetic force ball float is likely to result in deviation of reading, two is that existing conservator design margin is less than normal, causing summer high temperature reading higher, need to drain the oil, when winter temperature is on the low side, oil level lattice number falls to less than 0, cannot intuitively observe oil level, need to add in time oil.On the whole, existing oil level indicator principle is relatively big mainly by the oil level in ball float monitoring conservator and error, and reading is the most directly perceived.
Summary of the invention
The purpose of this utility model is to provide and a kind of can intuitively read oil pillow oil level and the less installation for transformer oil level auxiliary monitoring device of number of degrees error.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is:
A kind of installation for transformer oil level auxiliary monitoring device, for the oil level of the conservator being connected by union with transformator is carried out auxiliary monitoring, described installation for transformer oil level auxiliary monitoring device includes the fuel level sensor that at least can detect the oil level in described union, and described sensor connects with signal with the background monitoring system of described transformator.
Preferably, described union being provided with relay, described fuel level sensor is the sensor detecting the oil level in the part union between described conservator and described relay.
Preferably, during described fuel level sensor embeds described relay.
Preferably, described fuel level sensor is connected to the terminal box of described transformator by cable, then is connected to described background monitoring system by described terminal box by cable.
Preferably, described fuel level sensor is to set oil level threshold value the sensor according to detected oil level with the comparative result output unlike signal of set oil level threshold value, and described installation for transformer oil level auxiliary monitoring device also includes the alarm being connected with described fuel level sensor.
Preferably, described fuel level sensor is the sensor utilizing pressure principle
Owing to technique scheme is used, this utility model compared with prior art has the advantage that this utility model uses the fuel level sensor being connected with the background monitoring system of transformator, oil level can be read intuitively, when in conservator, oil level falls to be to remain to accurately read oil level under the zero point of himself oil level indicating gage, consequently facilitating conservator is refueled and the control of process of draining the oil.
Accompanying drawing explanation
Accompanying drawing 1 is the schematic diagram of existing transformator and conservator.
Accompanying drawing 2 is transformator and the schematic diagram of conservator with installation for transformer oil level auxiliary monitoring device of the present utility model.
In the figures above: 1, transformator；2, conservator；3, Buchholz relay；4, union；5, fuel level sensor；6, background monitoring system；7, cable；8, the terminal box of transformator；9, oil level indicating gage；10, ball float.
Detailed description of the invention
This utility model is further described by the embodiment shown in below in conjunction with the accompanying drawings.
Embodiment one: as shown in Figure 2, transformator 1 is connected by union 4 conservator 2, union 4 is provided with again Buchholz relay 3, thus realizes the compensation of transformer oil in transformator 1.
A kind of installation for transformer oil level auxiliary monitoring device for the oil level of the conservator 2 being connected with transformator 1 being carried out auxiliary monitoring by union 4, including the fuel level sensor 5 utilizing pressure principle, this fuel level sensor 5 is at least for detecting the oil level in union 4, the oil level of the community that union 4 and conservator 2 are constituted directly can also be detected, it connects with signal with the background monitoring system 6 of transformator 1, thus transmits detected oil level signal to background monitoring system 6 so that personnel are monitored.Generally, fuel level sensor 5 can embed in Buchholz relay 3, thus using Buchholz relay 3 position as basic point, detects the oil level in the oil level in the part union between conservator 2 with Buchholz relay 3 or this part union and be connected conservator 2.This fuel level sensor 5 is first connected to the terminal box 8 of transformator 1 by cable 7, then is connected to background monitoring system 6 by terminal box 8 by cable 7.
The oil level that can be realized in union 4 that transformator 1 connected and conservator 2 by above-mentioned installation for transformer oil level auxiliary monitoring device is detected intuitively, even if the oil level in conservator 2 is less than 0 point of himself oil level indicating gage 9, it still is able to detect the physical location of oil level, consequently facilitating guarantee that oil level enables higher than Buchholz relay 3 certain distance.
Further scheme is, fuel level sensor 5 uses and can set oil level threshold value the sensor according to detected oil level with the comparative result output unlike signal of set oil level threshold value, and installation for transformer oil level auxiliary monitoring device also includes the alarm being connected with fuel level sensor 5.When the oil level detected is less than the oil level threshold value instruction lower limit of the oil level indicating gage based on ball float 10 9 carried less than conservator 2 (this oil level threshold value be typically set at) set, being reported to the police by alarm, the personnel that notify carry out mending refueling operation in time.And when oil level is too high, it is also possible to set its prompting and carry out Oil drain operation.Alarm can be arranged at background monitoring system 6
Above-mentioned installation for transformer oil level auxiliary monitoring device can also increase fuel temperature measurement function by setting up oil temperature sensor, may be used for oil density correction, in order to accurately measuring level height.
Above-described embodiment only for technology of the present utility model design and feature are described, its object is to allow person skilled in the art will appreciate that content of the present utility model and to implement according to this, can not limit protection domain of the present utility model with this.All equivalence changes made according to this utility model spirit or modification, all should contain within protection domain of the present utility model.
