Abstract
The invention relates to a gas sample collection device for a gas relay. The gas sample collection device is characterized by mainly comprising a gas storage bag and a bidirectional needle head tube, wherein a rotary valve is arranged at a gas inlet of the gas storage bag; a valve opening is sleeved with a rubber cap; one end of the bidirectional needle head tube is inserted into the rubber cap at the valve opening of the rotary valve, and the other end of the bidirectional needle head tube is sleeved on another rubber cap at a gas outlet of the gas relay. Due to the bag-type gas storage device of the gas sample collection device, crushing can be avoided; due to the structure with the bidirectional needle head tube and the rubber caps, the gas sample collection is simple and feasible, and a gas sample can be prevented from escaping; repeated sampling is avoided; meanwhile, the gas sample collection device is simple in structure and convenient to carry and use.
Description
Technical field
The present invention relates to a kind of electrical equipment and detect aid, particularly a kind of gas relay gas sample collecting device for air.
Background technology
In the time having air accumulation in the gas relay of transformer, should gather its gas sample and carry out stratographic analysis, whether to exist fault and nature of trouble to judge according to the component of gas and content to transformer.Have the impact of different back dissolving rates for reducing different component, must within the short as far as possible time, also analyze as early as possible by extraction gas sample, gas sample also will keep in Dark Place simultaneously, in case gas changes under the effect of light.The gas sample collecting device for air using at present is normally made up of connection rubber tube, T-valve and glass syringe three parts.Use this device to gather after gas sample, need first rotate the direction of T-valve, make it to seal syringe port, then syringe is taken off from connection rubber tube together with T-valve, and then take off T-valve, use rubber cap instead and seal syringe port.This device complicated operation in gatherer process, glass syringe is easily cracked, and the distortion of easily overflowing of the gas sample of collection, affects the accuracy of stratographic analysis, thereby causes the erroneous judgement of transformer fault and nature of trouble thereof.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of simple to operate, service-strong gas relay gas sample collecting device for air is provided.
The object of the present invention is achieved like this: a kind of gas relay gas sample collecting device for air, it is characterized in that it is mainly made up of bladder tank and bidirectional needle head tube, the air intake opening of bladder tank is provided with rotary valve, valve port cover has rubber cap, the rubber cap of rotation valve port is inserted in bidirectional needle head tube one end, and the other end inserts on another rubber cap that can be enclosed within on gas relay gas outlet.
It is broken that bag-shaped gas storage device of the present invention can be avoided, and the structure that bidirectional needle head tube adds rubber cap makes to gather the easy to operation of gas sample, and can prevent the effusion of gas sample, avoids repeated sampling, and meanwhile, it is simple in structure, carries with easy to use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
As shown in Figure 1, the present invention is mainly made up of bladder tank 1, bidirectional needle head tube 2, and bladder tank can adopt aluminium foil multilayer complex films to make, and this kind of material can be broken, and the feature such as it is low to have permeability, and adsorbability is little, stable chemical nature.The air intake opening of bladder tank is provided with changeover valve, and this valve is to be made up of bonnet 3 and valve rod 4, and valve switch operates by valve rod, rotates counterclockwise on earth as opening, and clockwise rotates on earth as closing, and valve port is in the end of valve rod.On the end valve port of valve rod, cover has rubber cap 5, and rubber cap 5 is inserted in bidirectional needle head tube one end, and the other end inserts rubber cap 6, and rubber cap 6 can be enclosed within on the gas outlet 7 of gas relay.
When use, the gas outlet of gas relay is put to rubber cap, again bidirectional needle head tube is inserted, bidirectional needle head tube is connected as shown in Figure 1 with bladder tank, then rotate counterclockwise valve rod rotary valve is opened, the gas of gas relay just can enter bladder tank, and gas production reaches while needs, clockwise rotate valve rod rotary valve cuts out, then pull up the rubber cap on gas relay gas outlet.
