Problems solved by technology

However, the post oil switch is often installed on the field high-voltage overhead line pole. In order to effectively cut off the high-voltage load current, most of the existing technologies use manual opening. The 10KV post oil switch is manually opened, which has low efficiency and low safety and reliability.

Example Embodiment

[0022] The technical solutions of the present invention will be further described in detail below through specific implementations.

[0023] As attached figure 1 And figure 2 As shown, an automatic column oiling switch includes an operating mechanism, a transmission mechanism and a tripping mechanism. An opening electromagnet is fixedly installed under the opening pull ring on one side of the operating mechanism, and the other side of the operating mechanism A closing electromagnet is fixedly installed under the closing pull ring. The opening electromagnet and the closing electromagnet are respectively electrically connected with a charging and discharging module, and the charging and discharging module includes an energy storage capacitor and a rectifier circuit connected in sequence , Step-down resistor and fuse; the rectifier circuit is a single-phase full-wave bridge rectifier circuit. The operating mechanism is also provided with a micro travel switch and a counting device...

Abstract

The invention discloses an automatic column oil switch. The oil switch comprises an operation mechanism, a transmission mechanism and a tripping mechanism. An opening electromagnet is fixedly installed under an opening pull ring of one side of the operation mechanism. A closing electromagnet is fixedly installed under a closing pull ring of other side of the operation mechanism. The opening electromagnet and the closing electromagnet are electrically connected with a charging/discharging module. A micro journey switch and a counting device used for marking on-off frequency of the oil switch are arranged on the operation mechanism. After the closing electromagnet is charged, the closing pull ring is pulled to open the oil switch. The charging/discharging module is connected with a controller which is in communication connection with the counting device, a monitoring center and a prepayment high voltage metering meter. The oil switch is advantageous in that the oil switch is safe, reliable, high in work efficiency and high in economical applicability; the frequency of manual power off is low; and difficulty in electric bill retrieving is avoided.

Description

technical field [0001] The invention relates to the technical field of electric power control, in particular to an automatic column oiling switch. Background technique [0002] High-voltage oil switch (oil circuit breaker) is an important equipment in power plants and substations, which can cut off and close the no-load current and load current of high-voltage circuits and powered equipment. The main components of the oil switch include the conductive part, the operating mechanism, the transmission mechanism and the tripping mechanism. [0003] For large users with a capacity of 315kVA or more, high-supply and high-calculation electricity consumption methods should be implemented as much as possible, and a pre-payment system should be adopted. Users pay electricity fees first, and then use electricity. Quantitative power supply, electricity fees are exhausted, and power supply is suspended. However, the post oil switch is often installed on the field high-voltage overhead l...
