Background

The handcart is a main component in the withdrawable switch cabinet, and generally comprises a PT handcart and a switch handcart. The handcart is called a trolley, taking a switch handcart as an example, under the condition that a switch is broken, the handcart can be pulled out of the switch cabinet by hand after being paved with the guide rail, so as to be convenient for maintenance or replacement. It may be called a cart because it can be pulled out by hand and is shaped like a cart. The main elements on the handcart are primary electrical equipment such as a breaker, a transformer and the like. It has three positions in the switchgear: operation/test/disconnection. The handcart comprises a breaker handcart, a PT handcart, an isolation handcart, a fusing handcart, a metering handcart and the like.

However, the height difference between the wheels of the handcart and the ground is generally about 60mm, and the gravity center of the handcart is higher due to different slope guiding angles of various factories. When the wheels suddenly meet the blockage in the process of the handcart sliding down, the risk of overturning the handcart in front of and behind can be caused, and two main reasons of the overturning risk of the handcart are as follows: 1. the whole gravity center of the 35kV handcart is higher, and the overturning moment is relatively smaller when ascending and descending a slope; 2. the depth direction spacing of the wheels at the bottom of the 35kV handcart is relatively small, and the enough stability cannot be provided in the ascending and descending process.

According to the analysis of the overturning reasons, the adjustment of the central terrorism of the handcart relates to the design and the structural adjustment of the circuit breaker, and the overall feasibility is low, so that the technical problem needs to be solved.
