A cart type short circuit tester disclosed by the present invention comprises a cart body and a short circuit test system on the cart body, and the short circuit test system comprises an N-phase wiring bar, a U-phase wiring bar, a V-phase wiring bar, a W-phase wiring bar, a sliding connection mechanism, a switching-on and switching-off circuit and a test result indicating lamp. The U-phase wiring bar, the V-phase wiring bar and the W-phase wiring bar are used for being correspondingly connected with tested equipment or a tested circuit, a sliding groove is formed in the cart body, and the sliding connection mechanism is connected with two of the N-phase wiring bar, the U-phase wiring bar, the V-phase wiring bar and the W-phase wiring bar in a sliding mode along the sliding groove or connected with the U-phase wiring bar, the V-phase wiring bar and the W-phase wiring bar at the same time. The testing module is used for switching single-phase, two-phase or three-phase testing; and the switching-on and switching-off circuit is electrically connected with the U-phase wiring bar, the V-phase wiring bar and the W-phase wiring bar, and is used for short-circuiting the test phase lines of the tested equipment or the tested circuit. The device can be freely switched among a single-phase short-circuit test, a two-phase short-circuit test and a three-phase short-circuit test.
