Description
Technical field
The application belongs to and relates to a kind of SF6 equipment making-up air device in order to SF6 equipment to carry out according to on-the-spot superfeed pressure, temperature suitability tonifying Qi.
Background technology
Tradition SF6 tonifying Qi process takes to carve observes pressure indicator, and owing to being that Non-follow control very easily causes that tonifying Qi is excessive or deficient amount, gas-filled valve joint due to different equipment manufacturer is all inconsistent simultaneously, makes again gas-filled valve select length consuming time, seriously reduces working efficiency; In addition, when temperature is lower, SF6 easily liquefies, and causes tonifying Qi difficulty. Domestic existing SF6 intelligence making-up air device is a lot, and function is mutual difference also, and what have focuses on intelligence tonifying Qi, what have focuses on convenient in carrying, swift to operate, what have focuses on heating tonifying Qi, mainly develops for specific Working environment, all has certain Bureau sex-limited.
Prior art has no relevant report.
Summary of the invention
The object of the application is to propose a kind of to integrate tonifying Qi, heating, rapid abutting joint, the SF6 equipment making-up air device automatically weighed.
The object of the application is achieved in that SF6 equipment making-up air device comprises the base plate carrying SF6 gas cylinder, walking wheel it is equiped with in base plate corner, it is provided with weighing device bottom SF6 gas cylinder, SF6 gas cylinder side is provided with heating unit, at SF6 gas cylinder blowing mouth, place is communicated with pneumatic tube, it is equiped with in order to the ready-packaged joint with SF6 equipment gas supplementing opening rapid abutting joint in pneumatic tube another end, it is equiped with temperature sensor in close pneumatic tube inlet mouth, it is equiped with pressure transmitter in close pneumatic tube air outlet, described temperature sensor is connected with the 2nd direct-current contactor circuit, after the 2nd direct-current contactor, circuit is connected with to control heating unit and leads to, first temperature magnetic valve of open circuit, in order to control pneumatic tube conducting whether the 2nd temperature magnetic valve, and temperature alarm circuit, described pressure transmitter is connected with the first direct-current contactor circuit, and after the first direct-current contactor, circuit is connected with to control pneumatic tube conducting whether pressure solenoid valve, and pressure alarm circuit.
Owing to implementing technique scheme, the application while carrying out tonifying Qi, can gas temperature, residual content in Real-Time Monitoring SF6 gas cylinder, be that tonifying Qi work provides comparatively comprehensively data refer.The application is simple to operate, by change ready-packaged joint can fast with treat that tonifying Qi equipment completes to be connected.
Accompanying drawing illustrates: the concrete structure of the application is provided by following drawings and Examples:
Fig. 1 is SF6 equipment making-up air device schematic circuit.
Legend: 1, the first direct-current contactor, 2, the 2nd direct-current contactor, 3, temperature sensor, 4, heating unit, 5, temperature alarm circuit, 6, the first temperature magnetic valve, the 7, the 2nd temperature magnetic valve, 8, pressure transmitter, 9, pressure alarm circuit, 10, pressure solenoid valve, 11, pneumatic tube, 12, ready-packaged joint.
Embodiment: the application by the restriction of following embodiment, can not determine concrete enforcement mode according to the technical scheme of the application and practical situation.
Embodiment: as shown in Figure 1, SF6 equipment making-up air device comprises the base plate carrying SF6 gas cylinder, walking wheel it is equiped with in base plate corner, it is provided with weighing device bottom SF6 gas cylinder, SF6 gas cylinder side is provided with heating unit 4, at SF6 gas cylinder blowing mouth, place is communicated with pneumatic tube 11, it is equiped with in order to the ready-packaged joint 12 with SF6 equipment gas supplementing opening rapid abutting joint in pneumatic tube 11 another end, it is equiped with temperature sensor 3 in close pneumatic tube 11 inlet mouth, it is equiped with pressure transmitter 8 in close pneumatic tube 11 air outlet, described temperature sensor 3 is connected with the 2nd direct-current contactor 2 circuit, it is connected with to control heating unit 4 at the rear circuit of the 2nd direct-current contactor 2 to lead to, first temperature magnetic valve 6 of open circuit, in order to control pneumatic tube 11 conducting whether the 2nd temperature magnetic valve 7, and temperature alarm circuit 5, described pressure transmitter 8 is connected with the first direct-current contactor 1 circuit, and circuit is connected with to control pneumatic tube 11 conducting whether pressure solenoid valve 10 after the first direct-current contactor 2, and pressure alarm circuit 9.
Described first temperature magnetic valve 6 is set to normal open state, keeps heating unit 4 path normal operation; 2nd temperature magnetic valve 7 is set to normal open state, keeps airway 11 conducting, when temperature sensor 3 detects that in pneumatic tube 11, temperature is too high, 2nd direct-current contactor 2 adhesive, first temperature magnetic valve 6 action, is changed into closed state by normal open state, circuit breaker, heating unit 4 stops heating, 2nd temperature magnetic valve 7 action, airway 11 is closed, and stops gas transmission, temperature alarm circuit 5 works simultaneously, reminds gas temperature in airway 11 too high.
Described pressure solenoid valve 10 is set to normal open state, keep airway 11 conducting, after pressure transmitter 8 detects that in pneumatic tube 11, pressure reaches definite value, first direct-current contactor 1 adhesive, pressure solenoid valve 10 action, airway 11 is closed, and stops gas transmission, pressure alarm circuit 9 works simultaneously, reminds inflation complete.
