Cheng Tongxin.Specifically, the inside of the elaterometer 103 can be provided with a communication component, and the communication component is used for one
Client is communicated, and the data that elaterometer 103 detects are sent into client.So, operating personnel can be
Office is convenient and swift just it can be seen that the density case of insulating gas, realizes on-line monitoring.In addition, the elaterometer 103
It can be also used for detecting the moisture of insulating gas.Because the number of moisture in insulating gas also influences whether that gas is exhausted
The dielectric level and arc extinction performance of edge switch cubicle, accordingly it is also possible to be monitored to the moisture of insulating gas.Gas density
Wired connection can be used between meter 103 and client, wireless connection can also be used, can specifically be selected according to being actually needed
Select.The client of the present embodiment can also be arranged on the outside of gas-insulated cabinet, for example, a display, being capable of real-time display gas
The monitoring information of volume density meter 103.The client of the present embodiment can also be arranged on the place from gas-insulated cabinet farther out, with side
Convenient to operate personnel watch at a distance.
The information of gas gauge 102 and elaterometer 103 can mutually confirm, and meet different customer demands.
One end of the gas pipeline 104 of the present embodiment connects with gas container, one of the other end and a threeway 106
One end connects.The material of the gas pipeline 104 can select according to being actually needed, for example, metal.
Second end connection gas gauge 102 of the present embodiment threeway 106.One the 3rd end of the threeway 106 connects
Connect elaterometer 103.
The check valve 107 of the present embodiment is connected on gas pipeline 104, for controlling the interior insulation gas of gas pipeline 104
Circulation.For example, can end insulating gas by the check valve 107 flows to gas gauge 102 or elaterometer 103,
To facilitate the maintenance of gas gauge 102 or elaterometer 103.
As depicted in figs. 1 and 2, if gas container is the gas tank 101 of gas insulation switch cabinet, the one of gas pipeline 104
End is provided with a protuberance 105 being connected with each gas tank 101.Three gas tanks 101 are shown in Fig. 2, are set in each gas tank 101
It is equipped with breaker.As depicted in figs. 1 and 2, the one end of gas pipeline 104 away from gas gauge 102 and elaterometer 103 is set
Protuberance 105 is equipped with, the protuberance 105 equally can be gas pipeline form.The protuberance 105 portion corresponding to gas tank 101
Position is provided with stretched head 1051.Gas in each gas tank 101 can flow into protuberance 105 by the stretched head 1051, and then
Gas gauge 102 and elaterometer 103 are separately flowed into by gas pipeline 104.
Because gas tank 101 is as a closed container, the possibility of its gas leakage is smaller, and reliability is higher.Cause
This, can connect all gas tanks 101 using same gas pipeline 104.When some gas tank 101 goes wrong, user
It can be pinpointed the problems by gas gauge 102 or elaterometer 103, and then carry out service work.Using a flue
Road 104 connects the mode of all gas tanks 101, can save cost, and excessive part can be avoided to take gas-insulated and opened
Close space limited inside cabinet.
Gas container can also be a bus bar canister.Insulating gas is also provided with inside the bus bar canister.Such as Fig. 3 and Fig. 4 institutes
Show, if gas insulation switch cabinet is formed using connecting method, a bus bar canister may be spliced by multiple parts.Splicing
Position it is more, occur gas leakage probability it is larger.Therefore, corresponding a gas can be respectively provided with to each bus bar canister
102, elaterometers 103 of pressure gauge and a gas pipeline 104.For example, as shown in figure 4, gas container is three
It is individual.A phase in each corresponding three-phase in gas container, and with a corresponding gas gauge 102, one
Elaterometer 103 and a gas pipeline 104.So, a bus bar canister can individually be detected, if it find that asking
Topic, can accurately know which bus bar canister there is a problem, be easy to subsequent maintenance.
The gas insulation switch cabinet of the present embodiment can also include a three-position switch operation mechanism 201 and an open circuit
Device operating mechanism 202, as shown in Figure 2.Wherein, circuit breaker operation mechanism 202 is located under three-position switch operation mechanism 201
Side, gas gauge 102 and elaterometer 103 are respectively positioned on three-position switch operation mechanism 201 and circuit breaker operation mechanism 202
Between.Because operating mechanism needs to expose handle for operating personnel's operation, therefore operating mechanism is typically all opened close to gas-insulated
Close the outer surface of the preceding cabinet of cabinet.And the gas gauge 102 of pointer-type is due to needing to expose dial plate for operating personnel's reading letter
Breath, therefore, gas gauge 102 can be close to the settings of preceding cabinet.In order to ensure gas gauge 102 and elaterometer 103
The environment of detected insulating gas is consistent, it is necessary to make the position of gas gauge 102 and elaterometer 103 lean on as far as possible
Closely.Gas gauge 102 and elaterometer 103 can be arranged at the He of three-position switch operation mechanism 201 by the present embodiment

The running of his part.
Further, the distance between gas gauge 102 and threeway 106 be equal to elaterometer 103 and threeway 106 it
Between distance, in such manner, it is possible to as far as possible ensure that the insulating gas of identical environment separately flows into gas gauge 102 and elaterometer
103 so that the information detected by gas gauge 102 and elaterometer 103 is to be directed to identical gaseous environment, information it
Between can mutually refer to.The gaseous environment of the present embodiment is, for example, the flow velocity of gas, air pressure, density, temperature, humidity etc..
Alternatively, the gas-insulated part switch cubicle of the present embodiment also includes an alarm.The alarm and gas pressure
Meter 102 and elaterometer 103 connect.When the numerical value for detecting gas gauge 102 is less than the first predetermined threshold value, or detection
When being less than the second predetermined threshold value to the numerical value of elaterometer 103, alarm is sent.Certainly, to be on the safe side, can also examine
The numerical value for measuring gas gauge 102 is less than the first predetermined threshold value, and the numerical value of elaterometer 103 is less than the second predetermined threshold value
When, send alarm.The alarm can be that text information alarm either audible alarm is used in long-range client, can also
Alarm bell on triggering gas insulation switch cabinet sends sound, the communication equipment that can also be carried with to the related director of equipment
Warning message is sent, various ways can be specifically used, will not be repeated here.Alarm get gas gauge 102 or
The mode of elaterometer 103 has a lot, such as is obtained in real time from gas gauge 102 or elaterometer 103, and with it is pre-
The correspondingly predetermined threshold value first stored is compared, and will not be repeated here.
The alarm can carry out implementing monitoring to gas gauge 102 and/or elaterometer 103, realize automatic report
It is alert, to remind user to overhaul gas container in time.
According to the present embodiment, by setting gas gauge 102 and elaterometer simultaneously in gas insulation switch cabinet
103, pressure monitor and the density monitoring to insulating gas can be realized simultaneously, to ensure the performance of gas insulation switch cabinet.This
Outside, individual demand has also been provided the user.User can select one way in which to supervise insulating gas according to demand
Control, improve user's use feeling.
Preferred embodiment of the present utility model is these are only, it is all in this practicality not to limit the utility model
Within new spirit and principle, any modification, equivalent substitution and improvements made etc., guarantor of the present utility model should be included in
Within the scope of shield.
