Abstract
The invention discloses an air-pressure-type switch triggering device which comprises a cylinder, a piston body, a connecting rod and a conductive contact. The piston body is located in the cylinder and connected with the inner wall of the cylinder in a sliding mode, the piston rod divides the cylinder into a high-pressure side and a low-pressure side, the side face, located on the low-pressure side of the cylinder, of the piston body is connected with one end of the connecting rod, a reset spring wraps the connecting rod, one end of the reset spring is connected with the inner wall of the cylinder, the cylinder is additionally provided with an air exhaust valve, a positioning pin and an air inlet, and the air inlet is located at the high-pressure side of the cylinder and is connected with a high-pressure air pump through an air pipe. High-pressure gas and the spring serve as drive force for driving a high-pressure switch contact to be opened and closed, use of an electromagnetic coil is effectively avoided, the defect that a traditional electromagnetic coil is frequently damaged is avoided, requirements of normal work of the high-pressure switch contact are met, meanwhile, the failure rate of the equipment is greatly reduced, on one hand, operation stability of the equipment is improved, and on the other hand, operation cost of the equipment is reduced.
Description
Technical field
The present invention relates to a kind of pneumatic-typed switch trigger gear, belong to power switchgear technical field.
Background technique
At present, in electric power system, the service condition of high-voltage switch gear is very many, it is that the electromagnetic effect absorption iron core trigger switch mechanism producing by closing coil and switching winding realizes that the switching of high-voltage switch gear is at present closed, but in actual use, due to working environment poor insulativity, the situations such as the aging or high temperature of coil insulation, often there will be closing coil and switching winding to open circuit or the fault such as short circuit, when serious, cause coil thoroughly to burn and even cause fire, therefore need at ordinary times constantly to strengthen on the one hand maintenance and the inspection of coil, the opposing party also needs often coil to be changed, therefore when having caused the larger wasting of resources, also increased equipment operating cost.
Summary of the invention
The object of the invention is just to overcome above-mentioned deficiency, and a kind of pneumatic-typed switch trigger gear is provided.
For achieving the above object, the present invention is achieved through the following technical solutions:
A kind of pneumatic-typed switch trigger gear, described pneumatic-typed switch trigger gear is by cylinder, piston body, connecting rod, conductive contact forms, wherein piston body is positioned at cylinder internal and is slidably connected with cylinder inner wall, described piston body is divided into high pressure by cylinder and surveys and low voltage side, the piston body side that is wherein positioned at cylinder low voltage side is connected with connecting rod one end, and on connecting rod coated Returnning spring, described Returnning spring one end is connected with cylinder inner wall, the other end is connected with low voltage side piston body surface, the described connecting rod the other end is connected with conductive contact, and conductive contact is positioned at outside cylinder and is not less than 1 centimetre in distance between cylinders, on described cylinder, separately establish outlet valve, locating stud and suction port, described suction port is positioned at cylinder high pressure and surveys and be connected with high-pressure pump by tracheae, on described tracheae, separately establish solenoid valve, described locating stud is embedded in cylinder low voltage side and offsets with piston body surface, described outlet valve is positioned at cylinder high pressure side end.
