Problems solved by technology

In both types of construction however, the contact arms of the circuit breaker take up a lot of space
Also, due to the long contact arms of the circuit breaker, the cost of materials is also higher
Long contact arms result in longer current paths which cause power loss, heat generation and excessive material usage

Example Embodiment

[0018] The invention relates to a compact switchgear with a more simplified structure. More specifically, the present invention will be explained with reference to an exemplary embodiment.

[0019] figure 1 It is a schematic diagram of a traditional horizontal insulation switchgear 100, which includes a power cable 110, a converter 120 connected to the stationary contact 140 on the converter side, a jumper 130, and a bus bar 160 connected to the stationary contact 150 on the bus side. , Air passage 170, circuit breaker 180 and double shielding mechanism 190. The circuit breaker includes a circuit breaker pole 183 on which two contact arms 184 and 185 are located. The contact arms 184 and 185 have contacts 186 and 189, respectively. The contact 186 of the circuit breaker 180 can be electrically connected to the converter side contact 140. The contact 189 of the circuit breaker 180 can be electrically connected to the bus side contact 150. In addition, a vent 175 is provided on...

Abstract

The invention relates to a compact switchgear having more simplified construction. The switchgear of the invention comprises a circuit breaker and a monoblock. The monoblock is electrically connectible to the circuit breaker of the switchgear. The invention also provides a shutter arrangement for the compact switchgear of the invention. The invention further relates to a method of operating the switchgear having the shutter arrangement, of the invention.

Description

technical field [0001] The present invention relates to a switchgear and more particularly to a compact switchgear with a more simplified structure. Background technique [0002] Switchgear plays a key role in current electrical energy distribution systems. According to current plans, switchgear performs three main functions with respect to electrical energy distribution. These main functions are electrical protection, electrical insulation of installed sections and control. The electrical protection function of switchgear concerns the protection of circuit elements against thermal and mechanical stresses of short-circuit currents, the protection of persons in the event of an insulation failure, and the protection of appliances and devices supplied with electrical power. The electrical isolation function of switchgear involves de-energizing or isolating equipment to allow work to be done safely at the isolated part. The control function of the switchgear allows the operat...
