Abstract
The utility model discloses a three-phase flame explosion switch which belongs the explosion proof electric equipment of the power utilization apparatus, and the utility model is composed of an explosion proof box and a travel switch. When a contact pressure lever of the travel switch is pressurized, the contact pressure lever moves downwards to drive a moving contact and a fixed contact to be connected, causing an electric apparatus to work. The utility model has the advantages of simple structure, low cost, light weight and convenient operation.
Description
The utility model belongs to the electrical apparatus for explosive atmospheres of power device.
The automatic petrol filler explosion-proof electric apparatus that is used for the gas station at present, mainly form by travel switch and relay two large divisions, when the travel switch connection, the electrical appliance power supply is connected in the relay coil adhesive, make its work, this explosion-proof electric apparatus is the casting processing moulding, its complex structure, heaviness, owing to auxiliary relay has been arranged, has caused functional reliability low.
The purpose of this utility model provides a kind of simple in structure, and volume is little, safe and reliable travel switch.
The utility model is made up of armored cassette and travel switch, travel switch comprises contact depression bar, moving contact bar, decides contact bar, the contact depression bar that is installed in travel switch top links to each other with moving contact bar, the contact bar contact of deciding that is installed in the travel switch bottom dynamically joins with the moving contact bar contact that is installed in travel switch top, decides the other end stube cable line of contact bar contact.
The utility model compared with prior art, have simple in structure, advantage such as cost is low, and is in light weight easy to use, safe and reliable, it is reasonable in design, the advanced person.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the end view of Fig. 1.
Fig. 3 is an electrical schematic diagram of the present utility model.
Embodiment:
When butt joint presses bar (2) pressurization, contact depression bar (2) moves downward, and drives moving contact bar contact (4) and decide contact bar contact (6) to join, and connects circuit and uses electrical work, when control system is removed the pressure that is applied on the contact depression bar (2), reset.The other end and cable junction of deciding the contact bar contact of the present utility model sealed with epoxide-resin glue.
1 is armored cassette among the figure, and 3 are moving contact bar, and 5 for to decide contact bar, and 7 is explosion-proof lid, and 8 is cable, and 9 is the external connection box, and Sr is a lead-in, and SC is a lead-out wire.
Claims (2)
1, a kind of three-phase flame-proof switch of being made up of armored cassette and travel switch is characterized in that:
