The multi-gas-path intelligent SF6 density detection device is mainly and technically characterized by comprising a density relay, a gas collector, an intelligent control module, a plurality of spring mechanisms and a plurality of gas path valves, wherein the density relay and a gas outlet channel of the gas collector are installed together, the intelligent control module is connected with the plurality of gas path valves through the spring mechanisms respectively, the intelligent control module and the spring mechanisms are arranged inside the gas collector, the gas path valves are arranged on the gas collector, the gas collector is connected with a plurality of independent gas chambers through the plurality of gas path valves, and gas inlet channels are arranged between the gas path valves and the independent gas chambers. The multi-gas-path intelligent SF6 density detection device realizes a function of detecting the density of a plurality of gas paths through one density relay, is convenient to apply and simple to maintain, saves the investment, and overcomes the defect that other gas chambers are polluted if any one gas chamber fails when a plurality of gas chambers are communicated and share one density relay.
Description
Technical field
The utility model belongs to SF6 gas insulated metal enclosed swit chgear technical field, especially a kind of many gas circuits of gas insulated metal enclosed swit chgear SF6 density intelligent detection device.
Background technology
SF6 gas has good insulating property and arc extinguishing ability, and it is comparatively desirable insulation and arc-extinguishing medium under nominal situation, and therefore, SF6 gas is widely used in the high voltage electric power equip ment.The working pressure of SF6 gas and moisture height have direct impact to the safety and reliability of power equipment, moisture exceeds standard in density decline or the gas if the SF6 Leakage Gas causes, will there be potential safety hazard in high voltage electric power equip ment, even cause the generation of accident, therefore, the detection tool of gas insulated metal enclosed swit chgear gas density is of great significance.At present, most combined electrical apparatus manufacturer shares a density monitor with a plurality of air chambers by tracheae and detects for saving cost, because air chamber communicates all the time, when any one air chamber breaks down, certainly will other air chambers be polluted; Yet, if to the independent packing density relay of each independent air chamber of combined electrical apparatus, will cause the increase of cost of products, and increased the probability of combined electrical apparatus generation principal fault.
Summary of the invention
The purpose of this utility model is the technical deficiency that has remedied existing product, provide a kind of reasonable in design, cost is low and many gas circuits of gas insulated metal enclosed swit chgear SF6 density intelligent detection device of stable performance.
The purpose of this utility model realizes by following technological means:
A kind of many gas circuits of gas insulated metal enclosed swit chgear SF6 density intelligent detection device, comprise a density monitor, the gas collector-shoe gear, intelligent control module, a plurality of spring devices and a plurality of gas circuit valve, the outlet passageway of density monitor and gas collector-shoe gear is installed together, intelligent control module is connected with a plurality of gas circuit valves by a plurality of spring devices respectively, it is inner that intelligent control module and spring device are installed in the gas collector-shoe gear, this gas circuit valve is arranged on the gas collector-shoe gear, the gas collector-shoe gear is connected with a plurality of independent air chambers by a plurality of gas circuit valves, is provided with inlet channel between each gas circuit valve and each independent air chamber.
Advantage of the present utility model and good effect are:
The utility model is connected to a density monitor and multichannel independent air chamber on the gas collector-shoe gear, and respectively a plurality of air chambers are carried out Density Detection and demonstration by intelligent control module by cycle regular hour, realized using a density monitor to the Density Detection function of a plurality of gas circuits, it uses convenient, safeguard simple, the waste of not only having avoided each air chamber of combined electrical apparatus that a density monitor all is installed, saved investment, communicate but also eliminated a plurality of air chambers of combined electrical apparatus, when sharing a density monitor, any air chamber breaks down and pollutes the drawback of other air chambers.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is principle of work schematic diagram of the present utility model.
Embodiment
A kind of many gas circuits of gas insulated metal enclosed swit chgear SF6 density intelligent detection device, as shown in Figure 1, comprise a density monitor 1, gas collector-shoe gear 4, intelligent control module 3, a plurality of spring devices 5 and a plurality of gas circuit valve 6, the outlet passageway 2 of density monitor and gas collector-shoe gear is installed together, intelligent control module is connected with the gas circuit valve by spring device respectively, it is inner that intelligent control module and spring device are installed in the gas collector-shoe gear, this gas circuit valve is arranged on gas collector-shoe gear bottom, the gas collector-shoe gear is connected with a plurality of independent air chambers by a plurality of gas circuit valves, is provided with inlet channel 7 between gas circuit valve and each independent air chamber.The logical resistance of each spring device and gas circuit valve and each air chamber and density monitor is controlled in the intelligent control module timesharing, realizes the SF6 gas detection function to each air chamber.
The principle of work of this pick-up unit, as shown in Figure 2, intelligent control module is controlled the logical resistance function that each spring device is realized each gas circuit, and when a spring device promoted forward coupled gas circuit valve, this gas circuit valve goalkeeper carried out shutoff to the place gas circuit; When spring device was regained, this gas circuit was opened.Therefore can realize that density monitor only measures a gas circuit at every turn, namely only have an air chamber to communicate with density monitor, all the other gas circuits are all sealed.After a gas circuit detected and finishes, all gas circuit was all closed, and next gas circuit is opened subsequently, carries out Density Detection, and so circulation repeatedly.The gas density of each gas circuit detects the time of duration, the whole sealings of gas circuit and needs to detect which gas circuit, all can set by intelligent control module.For example, when 6. 1. gas circuit extremely all detected, at first, intelligent control module was controlled all spring devices and is ejected, stifled all gas circuits of all gas circuit valve door seals 0.5 second; The spring device compression 1. of subsequently intelligent control module control gas circuit, gas circuit gas circuit valve 1. is opened, and this gas circuit was connected 5 seconds, and density monitor detects gas circuit gas density 1.; After detection was finished, all gas circuits were all closed 0.5 second, then gas circuit 2. the gas circuit valve of passage be opened, density monitor detects the gas density of this gas circuit, by that analogy, cycle detection.When any gas circuit gas leakage or other reasons occur caused internal pressure to be lower than predefined threshold value, its corresponding air chamber carried out artificial tonifying Qi or low-voltage dead lock with low pressure alarming, to guarantee insulativity and the security of equipment.
It is emphasized that; embodiment described in the utility model is illustrative; rather than determinate; therefore the utility model is not limited to the embodiment described in the embodiment; every by those skilled in the art according to other embodiments that the technical solution of the utility model draws, belong to equally the scope of the utility model protection.
